Detail

Multiple memory management flaws were found in the GSSAPI library used by Kerberos that could result in the use of already freed memory or an attempt to free already freed memory, possibly leading to a crash or allowing the execution of arbitrary code (CVE-2007-5901, CVE-2007-5971).

A flaw was discovered in how the Kerberos krb5kdc handled Kerberos v4 protocol packets. An unauthenticated remote attacker could use this flaw to crash the krb5kdc daemon, disclose portions of its memory, or possibly %execute arbitrary code using malformed or truncated Kerberos v4 protocol requests (CVE-2008-0062, CVE-2008-0063).

This issue only affects krb5kdc when it has Kerberos v4 protocol compatibility enabled, which is a compiled-in default in all Kerberos versions that Mandriva Linux ships prior to Mandriva Linux 2008.0. Kerberos v4 protocol support can be disabled by adding v4_mode=none (without quotes) to the [kdcdefaults] section of /etc/kerberos/krb5kdc/kdc.conf.

A flaw in the RPC library as used in Kerberos' kadmind was discovered by Jeff Altman of Secure Endpoints. An unauthenticated remote attacker could use this vulnerability to crash kadmind or possibly execute arbitrary code in systems with certain resource limits configured; this does not affect the default resource limits used by Mandriva Linux (CVE-2008-0947).

The updated packages have been patched to correct these issues.

Title: DSA-1524 krb5 -- several vulnerabilities
Description: Several remote vulnerabilities have been discovered in the kdc component of the krb5, a system for authenticating users and services on a network. The Common Vulnerabilities and Exposures project identifies the following problems: An unauthenticated remote attacker may cause a krb4-enabled KDC to crash, expose information, or execute arbitrary code. Successful exploitation of this vulnerability could compromise the Kerberos key database and host security on the KDC host. An unauthenticated remote attacker may cause a krb4-enabled KDC to expose information. It is theoretically possible for the exposed information to include secret key data on some platforms. An unauthenticated remote attacker can cause memory corruption in the kadmind process, which is likely to cause kadmind to crash, resulting in a denial of service. It is at least theoretically possible for such corruption to result in database corruption or arbitrary code execution, though we have no such exploit and are not aware of any such exploits in use in the wild. In versions of MIT Kerberos shipped by Debian, this bug can only be triggered in configurations that allow large numbers of open file descriptors in a process.
