The GD library is prone to a buffer overflow vulnerability.
| Package | media-libs/gd on all architectures |
|---|---|
| Affected versions | < 2.0.35-r1 |
| Unaffected versions | >= 2.0.35-r1 |
GD is a graphic library for fast image creation.
Tomas Hoger reported that the _gdGetColors() function in gd_gd.c does not properly verify the colorsTotal struct member, possibly leading to a buffer overflow.
A remote attacker could entice a user to open a specially crafted image file with a program using the GD library, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service condition.
There is no known workaround at this time.
All GD users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.35-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are available since November 21, 2009. It is likely that your system is already no longer affected by this issue.
