Amazon Linux 2023 : memcached, memcached-devel, memcached-selinux (ALAS2023-2023-449)

critical Nessus Plugin ID 186970

Language:

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-449 advisory.

 In Memcached before 1.6.22, a buffer overflow exists when processing multiget requests in proxy mode, if there are many spaces after the get substring. (CVE-2023-46852)

 In Memcached before 1.6.22, an off-by-one error exists when processing proxy requests in proxy mode, if \n is used instead of \r\n. (CVE-2023-46853)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'dnf update memcached --releasever 2023.2.20231211' to update your system.
