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

critical Nessus Plugin ID 186970

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)

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.
