MDKSA-2002:050-glibc

by Nikola Strahija on August 14th, 2002 A buffer overflow vulnerability was found in the way that the glibc resolver handles the resolution of network names and addresses via DNS in glibc versions 2.2.5 and earlier. Only systems using the "dns" entry in the "networks" database in /etc/nsswitch.conf are vulnerable to this issue. By default, Mandrake Linux has this database set to "files" and is not vulnerable. Likewise, a similar bug is in the glibc-compat packages which provide compatability for programs compiled against 2.0.x versions of glibc.

To upgrade automatically, use MandrakeUpdate. The verification of md5
checksums and GPG signatures is performed automatically for you.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". A list of
FTP mirrors can be obtained from:

http://www.mandrakesecure.net/en/ftp.php

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:

rpm --checksig

All packages are signed by MandrakeSoft for security. You can obtain
the GPG public key of the Mandrake Linux Security Team from:

https://www.mandrakesecure.net/RPM-GPG-KEYS

Please be aware that sometimes it takes the mirrors a few hours to
update.
