Traceroute-nanog Update for Debian

Security 10944 Published by Philipp Esselbach 0

A new security update for Debian GNU/Linux is available:

DSA-254-1 traceroute-nanog -- buffer overflow

A vulnerability has been discovered in NANOG traceroute, an enhanced version of the Van Jacobson/BSD traceroute program. A buffer overflow occurs in the 'get_origin()' function. Due to insufficient bounds checking performed by the whois parser, it may be possible to corrupt memory on the system stack. This vulnerability can be exploited by a remote attacker to gain root privileges on a target host. Though, most probably not in Debian.

MDKSA-2003:023 : lynx

A vulnerability was discovered in lynx, a text-mode web browser. The HTTP queries that lynx constructs are from arguments on the command line or the $WWW_HOME environment variable, but lynx does not properly sanitize special characters such as carriage returns or linefeeds. Extra headers can be inserted into the request because of this, which can cause scripts that use lynx to fetch data from the wrong site from servers that use virtual hosting.

MDKSA-2003:020 : openssl
In an upcoming paper, Brice Canvel (EPFL), Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and Martin Vuagnoux (EPFL, Ilion) describe and demonstrate a timing-based attack on CBC ciphersuites in SSL and TLS.

MDKSA-2003:021 : krb5
A vulnerability was discovered in the Kerberos FTP client. When the client retrieves a file that has a filename beginning with a pipe character, the FTP client will pass that filename to the command shell in a system() call. This could allow a malicious remote FTP server to write to files outside of the current directory or even execute arbitrary commands as the user using the FTP client.

Mandrake Security Updates

Security 10944 Published by Philipp Esselbach 0

MandrakeSoft has released two new security updates for Mandrake Linux

MDKSA-2003:018 : apcupsd

A remote root vulnerability in slave setups and some buffer overflows in the network information server code were discovered by the apcupsd developers. They have been fixed in the latest unstable version, 3.10.5 which contains additional enhancements like USB support, and the latest stable version, 3.8.6.

There are a few changes that need to be noted, such as the port has changed from port 7000 to post 3551 for NIS, and the new config only allows access from the localhost. Users may need to modify their configuration files appropriately, depending upon their configuration.

MDKSA-2003:017 : pam

This can be exploited by a local attacker to gain access to the root user's X session. In order for it to be successfully exploited, the attacker would have to somehow get the root user to su to the account belonging to the attacker.
