CVE-2022-23943

An out-of-bounds read/write vulnerability was found in the mod_sed module of httpd. This flaw allows an attacker to overwrite the memory of an httpd instance that is using mod_sed with data provided by the attacker.

The mod_sed module is disabled by default on Red Hat Enterprise Linux 7 and 8. For this reason, the flaw has been rated as having a security impact of Moderate. The httpd package as shipped with Red Hat Enterprise Linux 6 is not affected by this flaw because the mod_sed module is available only in httpd 2.3 and later.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Disabling mod_sed and restarting httpd will mitigate this flaw. See https://access.redhat.com/articles/10649 for more information.
