GLSA-200511-21 : Macromedia Flash Player: Remote arbitrary code execution
Medium Nessus Plugin ID 20265
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200511-21 (Macromedia Flash Player: Remote arbitrary code execution)
When handling a SWF file, the Macromedia Flash Player incorrectly validates the frame type identifier stored in the SWF file which is used as an index to reference an array of function pointers. A specially crafted SWF file can cause this index to reference memory outside of the scope of the Macromedia Flash Player, which in turn can cause the Macromedia Flash Player to use unintended memory address(es) as function pointers.
An attacker serving a maliciously crafted SWF file could entice a user to view the SWF file and execute arbitrary code on the user's machine.
There is no known workaround at this time.
SolutionAll Macromedia Flash Player users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-plugins/adobe-flash-7.0.61'
