GLSA-200801-14 : Blam: User-assisted execution of arbitrary code

medium Nessus Plugin ID 30119

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-200801-14 (Blam: User-assisted execution of arbitrary code)

 The '/usr/bin/blam' script sets the 'LD_LIBRARY_PATH' environment variable incorrectly, which might result in the current working directory (.) being included when searching for dynamically linked libraries of the Mono Runtime application.
 Impact :

 A local attacker could entice a user to run Blam in a directory containing a specially crafted library file which could result in the execution of arbitrary code with the privileges of the user running Blam.
 Workaround :

 Do not run Blam from an untrusted working directory.

Solution

All Blam users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-news/blam-1.8.4'
