Debian DSA-039-1 : glibc

low Nessus Plugin ID 14876

Synopsis

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

Description

The version of GNU libc that was distributed with Debian GNU/Linux 2.2 suffered from 2 security problems :

 - It was possible to use LD_PRELOAD to load libraries that are listed in /etc/ld.so.cache, even for suid programs.
 This could be used to create (and overwrite) files which a user should not be allowed to.
 - By using LD_PROFILE suid programs would write data to a file to /var/tmp, which was not done safely. Again, this could be used to create (and overwrite) files which a user should not have access to.

Both problems have been fixed in version 2.1.3-17 and we recommend that you upgrade your glibc packages immediately.


Please note that a side-effect of this upgrade is that ldd will no longer work on suid programs, unless you logged in as root.

Solution

Upgrade the affected glibc package.
