A security vulnerability has been detected in SerenityOS up to 3d83e4509fd20d7438e1ae8470ffe668c136229c. Affected by this vulnerability is the function decode_bmp_pixel_data of the file Userland/Libraries/LibGfx/ImageFormats/BMPLoader.cpp of the component LibGfx. The manipulation of the argument height leads to integer overflow. The attack is possible to be carried out remotely. The attack's complexity is rated as high. The exploitation appears to be difficult. The exploit has been disclosed publicly and may be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The identifier of the patch is 007041bb2dd6d140c9e707caddfb0a49ecf96469.

Apr 26, 2023An issue was discovered in Serenity Serene (and StartSharp) before 6.7.0.CVE-2023-31287 · Other software · Serenity · reported by MITREHigh 7.8
An issue was discovered in Serenity Serene (and StartSharp) before 6.7.0. Password reset links are sent by email. A link contains a token that is used to reset the password. This token remains valid even after the password reset and can be used a second time to change the password of the corresponding user. The token expires only 3 hours after issuance and is sent as a query parameter when resetting. An attacker with access to the browser history can thus use the token again to change the password in order to take over the account.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
