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
Affected configurations
• apache http server (>= 2.4.0 <= 2.4.46)
• debian debian linux 9.0
• debian debian linux 10.0
• fedoraproject fedora 34
• fedoraproject fedora 35
• oracle enterprise manager ops center 12.4.0.0
• oracle instantis enterprisetrack 17.1
• oracle instantis enterprisetrack 17.2
• oracle instantis enterprisetrack 17.3
• oracle zfs storage appliance kit 8.8
