Debian DSA-1973-1 : glibc, eglibc - information disclosure

high Nessus Plugin ID 44838

Language:

Synopsis

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

Description

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.

Solution

Upgrade the glibc or eglibc package.

For the oldstable distribution (etch), this problem has been fixed in version 2.3.6.ds1-13etch10 of the glibc package.

For the stable distribution (lenny), this problem has been fixed in version 2.7-18lenny2 of the glibc package.
