Ubuntu Security Notice 1396-1 - It was discovered that the GNU C Library did not properly handle integer overflows in the timezone handling code. An attacker could use this to possibly execute arbitrary code by convincing an application to load a maliciously constructed tzfile. It was discovered that the GNU C Library did not properly handle passwd.adjunct.byname map entries in the Network Information Service (NIS) code in the name service caching daemon (nscd). An attacker could use this to obtain the encrypted passwords of NIS accounts. This issue only affected Ubuntu 8.04 LTS. Various other issues were also addressed.

Debian Linux Security Advisory 1973-1 - Christoph Pleger has discovered that the GNU C Library (aka glibc) and its derivatives add information from the passwd.adjunct.byname map to entries in the passwd map, which allows local users to obtain the encrypted passwords of NIS accounts by calling the getpwnam function.
