GLSA-200704-22 : BEAST: Denial of Service

high Nessus Plugin ID 25110

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-200704-22 (BEAST: Denial of Service)

 BEAST, which is installed as setuid root, fails to properly check whether it can drop privileges accordingly if seteuid() fails due to a user exceeding assigned resource limits.
 Impact :

 A local user could exceed his resource limit in order to prevent the seteuid() call from succeeding. This may lead BEAST to keep running with root privileges. Then, the local user could use the 'save as' dialog box to overwrite any file on the vulnerable system, potentially leading to a Denial of Service.
 Workaround :

 There is no known workaround at this time.

Solution

All BEAST users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=media-sound/beast-0.7.1'
