RHEL 2.1 / 3 : gdk-pixbuf (RHSA-2004:447)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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 (CVE-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 CVE-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. (CVE-2004-0782, CVE-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. (CVE-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.
