CVSS: 7.3EPSS: 0%CPEs: 10EXPL: 0CVE-2020-35452 – mod_auth_digest possible stack overflow by one nul byte
https://notcve.org/view.php?id=CVE-2020-35452
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 Apache HTTP Server versiones 2.4.0 a 2.4.46 Un Digest nonce especialmente diseñado puede causar un desbordamiento de pila en la función mod_auth_digest. No existe reportes de que este desbordamiento sea explotable, ni el equipo del Servidor HTTP Apache podría crear uno, aunque algún compilador y/o opción de compilación particular podría hacerlo posible, con consecuencias limitadas de todos modos debido al tamaño (un solo byte) y el valor (cero bytes) del desbordamiento A flaw was found in Apache httpd. The mod_auth_digest has a single zero byte stack overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://httpd.apache.org/security/vulnerabilities_24.html http://www.openwall.com/lists/oss-security/2021/06/10/5 https://lists.apache.org/thread.html/r7f2b70b621651548f4b6f027552f1dd91705d7111bb5d15cda0a68dd%40%3Cdev.httpd.apache.org%3E https://lists.apache.org/thread.html/rccb1b8225583a48c6360edc7a93cc97ae8b0215791e455dc607e7602%40%3Cannounce.httpd.apache.org%3E https://lists.apache.org/thread.html/re026d3da9d7824bd93b9f871c0fdda978d960c7e62d8c43cba8d0bf3%40%3Ccvs.httpd.apache.org%3E https://lists.debian.org/debian-lts-announce/2021/07/msg00006 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
