Adobe Acrobat Reader is a utility used to view PDF files.
A buffer overflow has been discovered in the UnixAppOpenFilePerform() function, which is called when Adobe Acrobat Reader tries to open a file with the "\Filespec" tag.
By enticing a user to open a specially crafted PDF document, a remote attacker could exploit this vulnerability to execute arbitrary code.
There is no known workaround at this time.
Since Adobe will most likely not update the 5.0 series of Adobe Acrobat Reader for Linux, all users should upgrade to the latest available version of the 7.0 series:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/acroread-7.0"
