DESCRIPTION Imlib is a library that allows X11 programs to use images of various file formats.
Alan Cox discovered some situations where a heap corruption[1] may occur when processing some malformed image. Al Viro found that imlib was falling back to the NetPBM library[2] when processing some kind of images, but NetPBM is not suitable to process untrusted image input.
An attacker could use a crafted image to exploit a program linked to imlib (like a mailer program or an image viewer) and cause a DoS or even remote code execution.
This update to imlib 1.9.14 solves both problems and adds some fixes from the imlib developers.
Notice that the update[3] for Conectiva Linux versions prior to 8 was released on 03/28/2002.
SOLUTION All users of imlib should do the upgrade. Notice that the vulnerabilities can be exploited through programs linked to imlib (like the "Electric Eyes" image viewer), so you should restart them in order to load the updated imlib.
ADDITIONAL INSTRUCTIONS Users of Conectiva Linux version 6.0 or higher may use apt to perform upgrades of RPM packages: - add the following line to /etc/apt/sources.list if it is not there yet (you may also use linuxconf to do this):
Currently there are no Talkback posted on "Conectiva Linux Announcement: imlib",
