FreeBSD : FreeBSD -- zlib heap buffer overflow (a1323a76-28f1-11ed-a72a-002590c1f29c)

critical Nessus Plugin ID 164514

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the a1323a76-28f1-11ed-a72a-002590c1f29c advisory.

- zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference). (CVE-2022-37434)

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

Solution

Update the affected packages.
