GLSA-200710-07 : Tk: Buffer overflow
Medium Nessus Plugin ID 26947
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200710-07 (Tk: Buffer overflow)
Reinhard Max discovered a boundary error in Tk when processing an interlaced GIF with two frames where the second is smaller than the first one.
A remote attacker could entice a user to open a specially crafted GIF image with a Tk-based software, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
SolutionAll Tk users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/tk-8.4.15-r1'
