An update for httpd is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1246 Final 1.0 1.0 2021-06-26 Initial 2021-06-26 2021-06-26 openEuler SA Tool V1.0 2021-06-26 httpd security update An update for httpd is now available for openEuler-20.03-LTS-SP1. Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant web server. Security Fix(es): In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server could cause a heap overflow(CVE-2021-26691) Apache HTTP Server versions 2.4.41 to 2.4.46 mod_proxy_http can be made to crash (NULL pointer dereference) with specially crafted requests using both Content-Length and Transfer-Encoding headers, leading to a Denial of Service(CVE-2020-13950) 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(CVE-2020-35452) Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with MergeSlashes OFF(CVE-2021-30641) An update for httpd is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of high.
