Description:
Martin Schulze has reported a vulnerability in Shadow, which can be exploited by malicious, local users to bypass certain security restrictions.
The vulnerability is caused due to an input validation error in the function "passwd_check()" in "libmisc/pwdcheck.c", which is used by the "chfn" and "chsh" utilities.
Successful exploitation allows unauthorised modification of account properties.
The vulnerability has been reported in version 4.0.4.1. Other versions may also be affected.
