Apr 9, 2024A buffer overflow vulnerability exists in all versions of sngrep since v0.4.2, due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers.CVE-2024-3119 · Other software · irontec · reported by 41c37e40-543d-43a2-b660-2fee83ea851aCritical 9
A buffer overflow vulnerability exists in all versions of sngrep since v0.4.2, due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers. The functions sip_get_callid and sip_get_xcallid in sip.c use the strncpy function to copy header contents into fixed-size buffers without checking the data length. This flaw allows remote attackers to execute arbitrary code or cause a denial of service (DoS) through specially crafted SIP messages.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the SIP ALG of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated network-based attacker to cause an integrity impact in connected networks. If the SIP ALG is configured and a device receives a specifically malformed SIP packet, the device prevents this packet from being forwarded, but any subsequently received retransmissions of the same packet are forwarded as if they were valid. This issue affects Juniper Networks Junos OS on SRX Series and MX Series: * 20.4 versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S4; * 21.3 versions prior to 21.3R3-S3; * 21.4 versions prior to 21.4R3-S2; * 22.1 versions prior to 22.1R2-S2, 22.1R3; * 22.2 versions prior to 22.2R2-S1, 22.2R3; * 22.3 versions prior to 22.3R1-S2, 22.3R2.

Oct 6, 2023PJSIP is a free and open source multimedia communication library written in C with high level API in C, C++, Java, C#, and Python languages.CVE-2023-38703 · Other software · pjsip · reported by GitHubCritical 9.8
PJSIP is a free and open source multimedia communication library written in C with high level API in C, C++, Java, C#, and Python languages. SRTP is a higher level media transport which is stacked upon a lower level media transport such as UDP and ICE. Currently a higher level transport is not synchronized with its lower level transport that may introduce use-after-free issue. This vulnerability affects applications that have SRTP capability (`PJMEDIA_HAS_SRTP` is set) and use underlying media transport other than UDP. This vulnerability’s impact may range from unexpected application termination to control flow hijack/memory corruption. The patch is available as a commit in the master branch.

May 26, 2023Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification.CVE-2023-32307 · Other software · freeswitch · reported by GitHubHigh 7.5
Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification. Referring to [GHSA-8599-x7rq-fr54](https://github.com/freeswitch/sofia-sip/security/advisories/GHSA-8599-x7rq-fr54), several other potential heap-over-flow and integer-overflow in stun_parse_attr_error_code and stun_parse_attr_uint32 were found because the lack of attributes length check when Sofia-SIP handles STUN packets. The previous patch of [GHSA-8599-x7rq-fr54](https://github.com/freeswitch/sofia-sip/security/advisories/GHSA-8599-x7rq-fr54) fixed the vulnerability when attr_type did not match the enum value, but there are also vulnerabilities in the handling of other valid cases. The OOB read and integer-overflow made by attacker may lead to crash, high consumption of memory or even other more serious consequences. These issue have been addressed in version 1.13.15. Users are advised to upgrade.

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.9 and 3.2.6, if `ds_is_in_list()` is used with an invalid IP address string (`NULL` is illegal input), OpenSIPS will attempt to print a string from a random address (stack garbage), which could lead to a crash. All users of `ds_is_in_list()` without the `$si` variable as 1st parameter could be affected by this vulnerability to a larger, lesser or no extent at all, depending if the data passed to the function is a valid IPv4 or IPv6 address string or not. Fixes will are available starting with the 3.1.9 and 3.2.6 minor releases. There are no known workarounds.

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.9 and 3.2.6, a malformed SIP message containing a large _Content-Length_ value and a specially crafted Request-URI causes a segmentation fault in OpenSIPS. This issue occurs when a large amount of shared memory using the `-m` flag was allocated to OpenSIPS, such as 10 GB of RAM. On the test system, this issue occurred when shared memory was set to `2362` or higher. This issue is fixed in versions 3.1.9 and 3.2.6. The only workaround is to guarantee that the Content-Length value of input messages is never larger than `2147483647`.

Mar 15, 2023OpenSIPS, a Session Initiation Protocol (SIP) server implementation, has a memory leak starting in the 2.3 branch and priot to versions 3.1.8 and 3.2.5.CVE-2023-28096 · Other software · OpenSIPS · reported by GitHubMedium 4.5
OpenSIPS, a Session Initiation Protocol (SIP) server implementation, has a memory leak starting in the 2.3 branch and priot to versions 3.1.8 and 3.2.5. The memory leak was detected in the function `parse_mi_request` while performing coverage-guided fuzzing. This issue can be reproduced by sending multiple requests of the form `{"jsonrpc": "2.0","method": "log_le`. This malformed message was tested against an instance of OpenSIPS via FIFO transport layer and was found to increase the memory consumption over time. To abuse this memory leak, attackers need to reach the management interface (MI) which typically should only be exposed on trusted interfaces. In cases where the MI is exposed to the internet without authentication, abuse of this issue will lead to memory exhaustion which may affect the underlying system’s availability. No authentication is typically required to reproduce this issue. On the other hand, memory leaks may occur in other areas of OpenSIPS where the cJSON library is used for parsing JSON objects. The issue has been fixed in versions 3.1.8 and 3.2.5.

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions prior to 3.1.7 and 3.2.4 have a potential issue in `msg_translator.c:2628` which might lead to a server crash. This issue was found while fuzzing the function `build_res_buf_from_sip_req` but could not be reproduced against a running instance of OpenSIPS. This issue could not be exploited against a running instance of OpenSIPS since no public function was found to make use of this vulnerable code. Even in the case of exploitation through unknown vectors, it is highly unlikely that this issue would lead to anything other than Denial of Service. This issue has been fixed in versions 3.1.7 and 3.2.4.

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, OpenSIPS crashes when a malformed SDP body is received and is processed by the `delete_sdp_line` function in the sipmsgops module. This issue can be reproduced by calling the function with an SDP body that does not terminate by a line feed (i.e. `\n`). The vulnerability was found while performing black-box fuzzing against an OpenSIPS server running a configuration that made use of the functions `codec_delete_except_re` and `codec_delete_re`. The same issue was also discovered while performing coverage guided fuzzing on the function `codec_delete_except_re`. The crash happens because the function `delete_sdp_line` expects that an SDP line is terminated by a line feed (`\n`): By abusing this vulnerability, an attacker is able to crash the server. It affects configurations containing functions that rely on the affected code, such as the function `codec_delete_except_re`.

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Prior to versions 3.1.7 and 3.2.4, sending a malformed `Via` header to OpenSIPS triggers a segmentation fault when the function `calc_tag_suffix` is called. A specially crafted `Via` header, which is deemed correct by the parser, will pass uninitialized strings to the function `MD5StringArray` which leads to the crash. Abuse of this vulnerability leads to Denial of Service due to a crash. Since the uninitialized string points to memory location `0x0`, no further exploitation appears to be possible. No special network privileges are required to perform this attack, as long as the OpenSIPS configuration makes use of functions such as `sl_send_reply` or `sl_gen_totag` that trigger the vulnerable code. This issue has been fixed in versions 3.1.7 and 3.2.4.

PJSIP is a free and open source multimedia communication library written in C. A buffer overflow vulnerability in versions 2.13 and prior affects applications that use PJSIP DNS resolver. It doesn't affect PJSIP users who do not utilise PJSIP DNS resolver. This vulnerability is related to CVE-2022-24793. The difference is that this issue is in parsing the query record `parse_query()`, while the issue in CVE-2022-24793 is in `parse_rr()`. A patch is available as commit `d1c5e4d` in the `master` branch. A workaround is to disable DNS resolution in PJSIP config (by setting `nameserver_count` to zero) or use an external resolver implementation instead.

Jan 19, 2023Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification.CVE-2023-22741 · Other software · freeswitch · reported by GitHubCritical 9.8
Sofia-SIP is an open-source SIP User-Agent library, compliant with the IETF RFC3261 specification. In affected versions Sofia-SIP **lacks both message length and attributes length checks** when it handles STUN packets, leading to controllable heap-over-flow. For example, in stun_parse_attribute(), after we get the attribute's type and length value, the length will be used directly to copy from the heap, regardless of the message's left size. Since network users control the overflowed length, and the data is written to heap chunks later, attackers may achieve remote code execution by heap grooming or other exploitation methods. The bug was introduced 16 years ago in sofia-sip 1.12.4 (plus some patches through 12/21/2006) to in tree libs with git-svn-id: http://svn.freeswitch.org/svn/freeswitch/trunk@3774 d0543943-73ff-0310-b7d9-9358b9ac24b2. Users are advised to upgrade. There are no known workarounds for this vulnerability.
