CVE-2020-35452

mod_auth_digest possible stack overflow by one nul byte

Published Jun 10, 2021 CVSS 3.1 · 7.3 High EPSS 53.2% KEV · Not listed
Description
Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team could create one, though some particular compiler and/or compilation option might make it possible, with limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow
