Fedora Core 2: 2024-411 Critical: gd Buffer Overflow Risk Update

fedora
Calendar Grey November 11, 2004
Scroller Fedora
Critical buffer overflows detected in gd library that could jeopardize Fedora; immediate upgrade is advised.
Several buffer overflows were reported in various memory allocation calls

Summary

The gd graphics library allows your code to quickly draw images

complete with lines, arcs, text, multiple colors, cut and paste from

other images, and flood fills, and to write out the result as a PNG or

JPEG file. This is particularly useful in Web applications, where PNG

and JPEG are two of the formats accepted for inline images by most

browsers. Note that gd is not a paint program.

Update Information:

Several buffer overflows were reported in various memory allocation calls. An attacker could create a carefully crafted image file in such a way that it could cause ImageMagick to execute arbitrary code when processing the image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0990 to these issues.

Whilst researching the fixes to these overflows, additional buffer overflows were discovered in calls to gdMalloc. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0941 to these issues.

Users of gd should upgrade to these updated packages, which contain a backported security patch, and are not vulnerable to these issues. * Thu Nov 04 2004 Phil Knirsch <pknirsch@redhat.com> 2.0.21-5.20.1

- Backport of fix for several buffer overflows in gdMalloc() calls
