Scientific Linux Security Update : gc on SL6.x i386/x86_64

Medium Nessus Plugin ID 70756


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


It was discovered that gc's implementation of the malloc() and calloc() routines did not properly perform parameter sanitization when allocating memory. If an application using gc did not implement application-level validity checks for the malloc() and calloc() routines, a remote attacker could provide specially crafted application-specific input, which, when processed by the application, could lead to an application crash or, potentially, arbitrary code execution with the privileges of the user running the application.

Applications using gc must be restarted for the update to take effect.


Update the affected gc, gc-debuginfo and / or gc-devel packages.
