RHSA-2004-447: gdk Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the gdk packages
Detailed Explanation for this Vulnerability Test
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. A possible hacker 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. A possible hacker 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.
A possible hacker 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.
