A number of possible buffer overruns were found in libraries included in the affected packages. A denial-of-service vulnerability was also found in the ksu program.
* A remote user may gain unauthorized root access to a machine running services authenticated with Kerberos 4.
* A remote user may gain unauthorized root access to a machine running krshd, regardless of whether the program is configured to accept Kerberos 4 authentication.
* A local user may gain unauthorized root access by exploiting v4rcp or ksu.
A packaging error was discovered in the original set of updates. This set of update packages includes no functional differences compared to the previously-released set.
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
