Synopsis

The remote Debian host is missing a security-related update.

Description

Several remote vulnerabilities have been discovered in the MIT reference implementation of the Kerberos network authentication protocol suite, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-2442 Wei Wang discovered that the free of an uninitialised pointer in the Kerberos RPC library may lead to the execution of arbitrary code.

- CVE-2007-2443 Wei Wang discovered that insufficient input sanitising in the Kerberos RPC library may lead to the execution of arbitrary code.

- CVE-2007-2798 It was discovered that a buffer overflow in the Kerberos administration daemon may lead to the execution of arbitrary code.

Solution

Upgrade the Kerberos packages.

For the old stable distribution (sarge) these problems have been fixed in version 1.3.6-2sarge5. Packages for hppa, mips and powerpc are not yet available. They will be provided later.

For the stable distribution (etch) these problems have been fixed in version 1.4.4-7etch2. Packages for hppa and mips are not yet available. They will be provided later.
