Scientific Linux Security Update : libuser on SL6.x i386/x86_64 (20150723)

medium Nessus Plugin ID 85210

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Two flaws were found in the way the libuser library handled the /etc/passwd file. A local attacker could use an application compiled against libuser (for example, userhelper) to manipulate the /etc/passwd file, which could result in a denial of service or possibly allow the attacker to escalate their privileges to root.
(CVE-2015-3245, CVE-2015-3246)

Solution

Update the affected packages.
