Mandriva Linux Security Advisory 2010-129

Posted Jul 8, 2010

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2010-129 - The krshd and v4rcp applications in MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion. The ftpd and ksu programs in MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, and Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which might allow local users to gain privileges by causing setuid to fail to drop privileges. Certain invalid GSS-API tokens can cause a GSS-API acceptor (server) to crash due to a null pointer dereference in the GSS-API library. The updated packages have been patched to correct these issues.
