PACKAGE   : sasl2
SUMMARY   : Fix for buffer overflow vulnerability
DATE      : 2004-11-11 15:16:00
ID        : CLA-2004:889
RELEVANT
RELEASES  : 9, 10

DESCRIPTION
 SASL[1] is the Simple Authentication and Security Layer, a method for
 adding authentication support to connection-based protocols.
 
 A vulnerability[2] has been discovered in the Cyrus implementation of
 the SASL library. The library honors the environment variable
 SASL_PATH blindly, which allows a local attacker to link against a
 malicious library to run arbitrary code with the privileges of a
 setuid or setgid application.


SOLUTION
 It is recommended that all sasl2 users upgrade their packages.
 
 IMPORTANT: If you are using Conectiva Linux 9, it is important to
 restart saslauthd daemon after upgrading the packages, in order to
 really fix the vulnerability.
