Fedora 7 : tk-8.4.13-6.fc7 (2007-2564)
Medium Nessus Plugin ID 27778
SynopsisThe remote Fedora host is missing a security update.
DescriptionBuffer overflow in the ReadImage function in generic/tkImgGIF.c in Tcl (Tcl/Tk) before 8.4.16 allows remote attackers to execute arbitrary code via multi-frame interlaced GIF files in which later frames are smaller than the first.
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected tk, tk-debuginfo and / or tk-devel packages.
