GLSA-201405-19 : MCrypt: User-assisted execution of arbitrary code
Medium Nessus Plugin ID 74061
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201405-19 (MCrypt: User-assisted execution of arbitrary code)
Multiple vulnerabilities have been discovered in MCrypt:
A boundary error in MCrypt could cause a stack-based buffer overflow (CVE-2012-4409).
MCrypt contains multiple format string errors (CVE-2012-4426).
MCrypt does not properly handle long file names, which could cause a stack-based buffer overflow (CVE-2012-4527).
A remote attacker could entice a user to open a specially crafted file using MCrypt, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
SolutionAll MCrypt users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-crypt/mcrypt-2.6.8-r2'
