high Nessus Plugin ID 20314

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200512-05 (Xmail: Privilege escalation through sendmail)

 iDEFENSE reported that the AddressFromAtPtr function in the sendmail program fails to check bounds on arguments passed from other functions, and as a result an exploitable stack overflow condition occurs when specifying the '-t' command line option.
 Impact :

 A local attacker can make a malicious call to sendmail, potentially resulting in code execution with elevated privileges.
 Workaround :

 There is no known workaround at this time.

Solution

All Xmail users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=mail-mta/xmail-1.22'
