Martin Schulze reported a vulnerability[2] in the passwd_check() function in "libmisc/pwdcheck.c" which is used by chfn and chsh and thus may allow a local attacker to use them to change the standard shell of other users or modify their GECOS information (full name, phone number...). SOLUTION It is recommended that all Conectiva Linux users upgrade their packages.
