Azure Linux 3.0 Security Update: cloud-hypervisor-cvm / crash / zlib (CVE-2022-37434)

critical Nessus Plugin ID 215940

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of cloud-hypervisor-cvm / crash / zlib installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-37434 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.
