AnalysisAI
An issue was discovered in libSDL2.a in Simple DirectMedia Layer (SDL) 2.0.9 when used in conjunction with libSDL2_image.a in SDL2_image 2.0.4. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. An issue was discovered in libSDL2.a in Simple DirectMedia Layer (SDL) 2.0.9 when used in conjunction with libSDL2_image.a in SDL2_image 2.0.4. There is a SEGV in the SDL function SDL_free_REAL at stdlib/SDL_malloc.c. Affected products include: Libsdl Sdl2 Image, Libsdl Simple Directmedia Layer, Fedoraproject Fedora, Canonical Ubuntu Linux, Opensuse Backports Sle.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
