K58003591 : Apache HTTP server vulnerability CVE-2022-28614

Security Advisory Description

The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use the ‘ap_rputs’ function and may pass it a very large (INT_MAX or larger) string must be compiled against current headers to resolve the issue. (CVE-2022-28614)

Impact

A very large input to the ap_rputs andap_rwrite functions can lead to an integer overflow and result in an out-of-bounds read. Integer overflow or wraparound may lead to exposure of sensitive information to an unauthorized actor.
