Debian DLA-598-1 : suckless-tools security update

high Nessus Plugin ID 93053

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the slock screen locking tool would segfault when the user's account had been disabled.

slock called crypt(3) and used the return value for strcmp(3) without checking to see if the return value of crypt(3) was a NULL pointer. If the hash returned by (getspnam()->sp_pwdp) was invalid, crypt(3) would return NULL and set errno to EINVAL. This would cause slock to segfault which leaves the machine unprotected.

For Debian 7 'Wheezy', this issue has been fixed in suckless-tools version 38-2+deb7u1.

We recommend that you upgrade your suckless-tools packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected suckless-tools package.
