GLSA-200802-01 : SDL_image: Two buffer overflow vulnerabilities
Critical Nessus Plugin ID 30243
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200802-01 (SDL_image: Two buffer overflow vulnerabilities)
The LWZReadByte() function in file IMG_gif.c and the IMG_LoadLBM_RW() function in file IMG_lbm.c each contain a boundary error that can be triggered to cause a static buffer overflow and a heap-based buffer overflow. The first boundary error comes from some old vulnerable GD PHP code (CVE-2006-4484).
A remote attacker can make an application using the SDL_image library to process a specially crafted GIF file or IFF ILBM file that will trigger a buffer overflow, resulting in the execution of arbitrary code with the permissions of the application or the application crash.
There is no known workaround at this time.
SolutionAll SDL_image users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/sdl-image-1.2.6-r1'
