Insight
Insight
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.
