VCID-qz6b-x9ps-aaae
Aliases: 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 |
Affected by 3 other vulnerabilities. Affected by 4 other vulnerabilities. Affected by 6 other vulnerabilities. |
|
VCID-t7fa-jbkc-aaab
Aliases: CVE-2021-44224 |
A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). |
Affected by 4 other vulnerabilities. |
|
VCID-ytrc-wygq-aaaf
Aliases: CVE-2020-9490 |
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. |
Affected by 3 other vulnerabilities. |
|
VCID-z9au-scjh-aaae
Aliases: CVE-2021-33193 |
