Description

This security bulletin contains information about 1 security vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2022-28615)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the ap_strcmp_match() function when processing an extremely large input buffer. A remote attacker can send a specially crafted HTTP request to the web server, trigger an out-of-bounds read error and read contents of memory on the system.

Note, the code distributed with the Apache HTTP Server cannot be coerced into such a call. The vulnerability can affect third-party modules or lua scripts that use ap_strcmp_match().
