This update fixes two security problems in imlib2.

Specially crafted xpm files could trigger a stack based buffer overflow in imlib2 which could potentially be exploited to execute arbitrary code. (CVE-2008-2426)

A crash in PNM handling due to a NULL pointer dereference was fixed.

This update fixes two security problems in imlib2.

Specially crafted xpm files could trigger a stack based buffer overflow in imlib2 which could potentially be exploited to execute arbitrary code (CVE-2008-2426).

A crash in PNM handling due to a NULL pointer dereference was fixed.

Stefan Cornelius discovered two buffer overflows in Imlib's image loaders for PNM and XPM images, which could possibly result in the execution of arbitrary code (CVE-2008-2426).

The updated packages have been patched to prevent this issue.

Fix CVE-2008-2426 / SA30401 - buffer overflow in the XPM loader.

It was discovered that Imlib2 did not correctly handle certain malformed XPM and PNG images. If a user were tricked into opening a specially crafted image with an application that uses Imlib2, an attacker could cause a denial of service and possibly execute arbitrary code with the user's privileges.

The remote host is affected by the vulnerability described in GLSA-200806-03 (Imlib 2: User-assisted execution of arbitrary code)

    Stefan Cornelius (Secunia Research) reported two boundary errors in     Imlib2:
    One of them within the load() function in the     file src/modules/loaders/loader_pnm.c when processing the header of a     PNM image file, possibly leading to a stack-based buffer overflow.
    The second one within the load() function in the file     src/modules/loader_xpm.c when processing an XPM image file, possibly     leading to a stack-based buffer overflow.
  Impact :

    A remote attacker could entice a user to open a specially crafted PNM     or XPM image, possibly resulting in the execution of arbitrary code     with the rights of the user running the application using Imlib 2.
  Workaround :

    There is no known workaround at this time.

Stefan Cornelius discovered two buffer overflows in Imlib's - a powerful image loading and rendering library - image loaders for PNM and XPM images, which may result in the execution of arbitrary code.
