Package name heimdal
Date December 6th, 2007
Advisory ID MDKSA-2007:239
Affected versions CS4.0

Problem Description

It was found that the gss_userok() function in Heimdal 0.7.2 did not
allocate memory for the ticketfile pointer before calling free(), which
could possibly allow remote attackers to have an unknown impact via an
invalid username. It is uncertain whether or not this is exploitable,
however packages are being provided regardless.

The updated packages have been patched to correct these issues.
