Updated gdk-pixbuf packages that fix several security flaws are now available.
The gdk-pixbuf package contains an image loading library used with the GNOME GUI desktop environment. [Updated 15th September 2004] Packages have been updated to correct a bug which caused the xpm loader to fail. During testing of a previously fixed flaw in Qt (CAN-2004-0691), a flaw was discovered in the BMP image processor of gdk-pixbuf. An attacker could create a carefully crafted BMP file which would cause an application to enter an infinite loop and not respond to user input when the file was opened by a victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0753 to this issue. During a security audit, Chris Evans discovered a stack and a heap overflow in the XPM image decoder. An attacker could create a carefully crafted XPM file which could cause an application linked with gtk2 to crash or possibly execute arbitrary code when the file was opened by a victim. (CAN-2004-0782, CAN-2004-0783) Chris Evans also discovered an integer overflow in the ICO image decoder. An attacker could create a carefully crafted ICO file which could cause an application linked with gtk2 to crash when the file is opened by a victim. (CAN-2004-0788) These packages have also been updated to correct a bug which caused the xpm loader to fail. Users of gdk-pixbuf are advised to upgrade to these packages, which contain backported patches and are not vulnerable to these issues.
