Resource Exhaustion Affecting buildah package, versions <1:1.31.3-1.el9

Note: Versions mentioned in the description apply only to the upstream buildah package and not the buildah package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. With fix, header parsing now correctly allocates only the memory required to hold parsed headers.
