F5 Networks BIG-IP : GnuPG vulnerability (K21284031)

medium Nessus Plugin ID 100179

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The do_uncompress function in g10/compress.c in GnuPG 1.x before 1.4.17 and 2.x before 2.0.24 allows context-dependent attackers to cause a denial of service (infinite loop) via malformed compressed packets, as demonstrated by an a3 01 5b ff byte sequence.
(CVE-2014-4617)

Impact

ARX

This vulnerability is exposed when using the Auto Diagnostics feature.

BIG-IP

GNU Privacy Guard (GnuPG) is not used in traffic processing. GnuPG is used only in administrative functions on the BIG-IP system, such as encryption of user configuration set (UCS) and single configuration files (SCF), and verification of ISOs and ASM signatures, which are not affected by this vulnerability. An authenticated ( root ) user with advanced shell access could upload a speciallycrafted file and execute gpg manually to trigger this vulnerability.

F5 iWorkflow, BIG-IQ, and Enterprise Manager

An authenticated user with advanced shell access could be able to exploit this vulnerability by executing gpg manually.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K21284031.
