high Nessus Plugin ID 160396

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 / 16.1.4 / 17.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the K91589041 advisory.

- In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
(CVE-2021-45960)

- lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22825)

- nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.
(CVE-2022-22826)

- storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. (CVE-2022-22827)

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

Solution
