Azure Linux 3.0 Security Update: libmemcached-awesome (CVE-2023-27478)

medium Nessus Plugin ID 215649

Synopsis

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

Description

The version of libmemcached-awesome 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-2023-27478 advisory.

 - libmemcached-awesome is an open source C/C++ client library and tools for the memcached server.
 `libmemcached` could return data for a previously requested key, if that previous request timed out due to a low `POLL_TIMEOUT`. This issue has been addressed in version 1.1.4. Users are advised to upgrade. There are several ways to workaround or lower the probability of this bug affecting a given deployment. 1: use a reasonably high `POLL_TIMEOUT` setting, like the default. 2: use separate libmemcached connections for unrelated data. 3: do not re-use libmemcached connections in an unknown state. (CVE-2023-27478)

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.
