Title
mod_auth_digest possible stack overflow by one nul byte
Summary
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
Severity
No CVSS data available.
CWE
- mod_auth_digest possible stack overflow by one nul byte
