Red Hat: 2014:1172-01 Critical: Procmail Heap Overflow Risk Alert

red hat
Calendar Grey September 10, 2014
Scroller Redhat
Newly released procmail updates for Red Hat have been issued to rectify a significant security vulnerability deemed critical in its implications.
Updated procmail packages that fix one security issue are now available for Red Hat Enterprise Linux 5, 6, and 7

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258

Summary

The procmail program is used for local mail delivery. In addition to just delivering mail, procmail can be used for automatic filtering, presorting, and other mail handling jobs.
A heap-based buffer overflow flaw was found in procmail's formail utility. A remote attacker could send an email with specially crafted headers that, when processed by formail, could cause procmail to crash or, possibly, execute arbitrary code as the user running formail. (CVE-2014-3618)
All procmail users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
