GLSA-200510-26 : XLI, Xloadimage: Buffer overflow
Medium Nessus Plugin ID 21275
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200510-26 (XLI, Xloadimage: Buffer overflow)
When XLI or Xloadimage process an image, they create a new image object to contain the new image, copying the title from the old image to the newly created image. Ariel Berkman reported that the 'zoom', 'reduce', and 'rotate' functions use a fixed length buffer to contain the new title, which could be overwritten by the NIFF or XPM image processors.
A malicious user could craft a malicious XPM or NIFF file and entice a user to view it using XLI, or manipulate it using Xloadimage, potentially resulting in the execution of arbitrary code with the permissions of the user running XLI or Xloadimage.
There is no known workaround at this time.
SolutionAll XLI users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/xli-1.17.0-r2' All Xloadimage users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-gfx/xloadimage-4.1-r4'
