Buffer overflow in the LWZReadByte function in IMG_gif.c in SDL_image before 1.2.7 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted GIF file, a similar issue to CVE-2006-4484. NOTE: some of these details are obtained from third party information.

The LWZReadByte() and IMG_LoadLBM_RW() functions in SDL_image contain a boundary error that could be triggered to cause a static buffer overflow and a heap-based buffer overflow. If a user using an application linked against the SDL_image library were to open a carefully crafted GIF or IFF ILBM file, the application could crash or possibly allow for the execution of arbitrary code.

The updated packages have been patched to correct this issue.

Secunia reports :

Two vulnerabilities have been reported in SDL_image, which can be exploited by malicious people to cause a Denial of Service or potentially compromise an application using the library.

A boundary error within the LWZReadByte() function in IMG_gif.c can be exploited to trigger the overflow of a static buffer via a specially crafted GIF file.

A boundary error within the 'IMG_LoadLBM_RW()' function in IMG_lbm.c can be exploited to cause a heap-based buffer overflow via a specially crafted IFF ILBM file.

Michael Skladnikiewicz discovered that SDL_image did not correctly load GIF images. If a user or automated system were tricked into processing a specially crafted GIF, a remote attacker could execute arbitrary code or cause a crash, leading to a denial of service.
(CVE-2007-6697)

David Raulo discovered that SDL_image did not correctly load ILBM images. If a user or automated system were tricked into processing a specially crafted ILBM, a remote attacker could execute arbitrary code or cause a crash, leading to a denial of service. (CVE-2008-0544).

The 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).
  Impact :

    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.
  Workaround :

    There is no known workaround at this time.

Several local/remote vulnerabilities have been discovered in the image loading library for the Simple DirectMedia Layer 1.2. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-6697     Gynvael Coldwind discovered a buffer overflow in GIF     image parsing, which could result in denial of service     and potentially the execution of arbitrary code.

  - CVE-2008-0544     It was discovered that a buffer overflow in IFF ILBM     image parsing could result in denial of service and     potentially the execution of arbitrary code.
