Debian DLA-2304-1 : libpam-radius-auth security update

high Nessus Plugin ID 139247

Language:

Synopsis

The remote Debian host is missing a security update.

Description

`add_password` in pam_radius_auth.c in pam_radius 1.4.0 does not correctly check the length of the input password, and is vulnerable to a stack-based buffer overflow during memcpy(). An attacker could send a crafted password to an application (loading the pam_radius library) and crash it. Arbitrary code execution might be possible, depending on the application, C library, compiler, and other factors.

For Debian 9 stretch, this problem has been fixed in version 1.3.16-5+deb9u1.

We recommend that you upgrade your libpam-radius-auth packages.

For the detailed security status of libpam-radius-auth please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libpam-radius-auth

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 libpam-radius-auth package.
