|Gentoo Linux Security Advisory
Title: Tk: Buffer overflow (GLSA 200710-07)
Date: October 07, 2007
A buffer overflow vulnerability has been discovered in Tk.
Tk is a toolkit for creating graphical user interfaces.
Vulnerable: < 8.4.15-r1
Unaffected: >= 8.4.15-r1
Architectures: All supported architectures
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.
All Tk users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/tk-8.4.15-r1"
