F5 Networks BIG-IP : glibc vulnerability (K08641512)

medium Nessus Plugin ID 154685

Language:

Synopsis

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

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 15.1.9 / 16.1.5 / 17.1.2. It is, therefore, affected by a vulnerability as referenced in the K08641512 advisory.

 The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite loop in applications, resulting in a denial of service, a different vulnerability from CVE-2016-10228.(CVE-2020-27618)ImpactWhen the infinite loop can be influenced by an attacker, this weakness could allow attackers to consume excessive resources such as CPU or memory resulting in a denial of service (DoS).

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K08641512.
