[GLSA-200405-12] CVS heap overflow vulnerability Vulnerability Scan
Vulnerability Scan Summary
CVS heap overflow vulnerability
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200405-12
(CVS heap overflow vulnerability)
Stefan Esser discovered a heap overflow in the CVS server, which can be
triggered by sending malicious "Entry" lines and manipulating the flags
related to that Entry. This vulnerability was proven to be exploitable.
Impact
A remote attacker can execute arbitrary code on the CVS server, with the
rights of the CVS server. By default, Gentoo uses the "cvs" user to run the
CVS server. In particular, this flaw allows a complete compromise of CVS
source repositories. If you're not running a server, then you are not
vulnerable.
Workaround
There is no known workaround at this time. All users are advised to upgrade
to the latest available version of CVS.

# emerge sync
