GLSA-200907-09 : Cyrus-SASL: Execution of arbitrary code

High Nessus Plugin ID 39780

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-200907-09 (Cyrus-SASL: Execution of arbitrary code)

James Ralston reported that in certain situations, Cyrus-SASL does not properly terminate strings which can result in buffer overflows when performing Base64 encoding.
Impact :

A remote unauthenticated user might send specially crafted packets to a daemon using Cyrus-SASL, possibly resulting in the execution of arbitrary code with the privileges of the user running the daemon or a Denial of Service.
Workaround :

There is no known workaround at this time.

Solution

All Cyrus-SASL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/cyrus-sasl-2.1.23'
