Http_server, Fedora, Enterprise_manager_ops_center, Instantis_enterprisetrack, Zfs_storage_appliance_kit 5.3
2021-06-10 CVE-2021-26691 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 Http_server, Debian_linux, Fedora, Enterprise_manager_ops_center, Instantis_enterprisetrack, Zfs_storage_appliance_kit 9.8

2021-06-10 CVE-2020-13950 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 Http_server, Debian_linux, Fedora, Enterprise_manager_ops_center, Instantis_enterprisetrack, Zfs_storage_appliance_kit 7.5
2021-06-10 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 Http_server, Debian_linux, Fedora, Enterprise_manager_ops_center, Instantis_enterprisetrack, Zfs_storage_appliance_kit 7.3

2021-10-05 CVE-2021-41773 A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in... Http_server, Fedora 7.5
