Liam Helmer noticed that sudo, a program that provides limited super user privileges to specific users, does not clean the environment sufficiently. Bash functions and the CDPATH variable are still passed through to the program running as privileged user, leaving possibilities to overload system routines.

Debian: bnc buffer overflow

Leon Juranic discovered that BNC, an IRC session bouncing proxy, does not always protect buffers from being overwritten. This could exploited by a malicious IRC server to overflow a buffer of limited size and execute arbitrary code on the client host.

Debian: shadow unintended behaviour fix

A vulnerability has been discovered in the shadow suite which provides programs like chfn and chsh. It is possible for a user, who is logged in but has an expired password to alter his account information with chfn or chsh without having to change the password. The problem was originally thought to be more severe.
