Title
Apache HTTP Server: mod_auth_digest one-time-nonce replay attack
Summary
Authentication bypass by capture-replay in mod_auth_digest in Apache Software Foundation Apache HTTP Server 2.4.x on all platforms allows a man-in-the-middle (MITM) attacker to replay captured digest authentication credentials via crafted requests that trigger garbage collection of the client's shared memory entry when AuthDigestNonceLifetime is set to 0.
Users are recommended to upgrade to version 2.4.69, which fixes this issue.

Title
Apache HTTP Server: mod_xml2enc crash on charset conversion failure
Summary
A NULL pointer dereference in mod_xml2enc in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an untrusted backend server to cause a denial of service via a proxied response with a charset whose conversion partially succeeds then fails.
Users are recommended to upgrade to version 2.4.69, which fixes this issue.

Apache HTTP Server: mod_proxy_ftp PASV address handling
Summary
Improper validation of FTP PASV reply address in mod_proxy_ftp in Apache Software Foundation Apache HTTP Server through 2.4.68 on all platforms allows, in forward proxy configurations, an untrusted FTP server to cause the proxy to open a data connection to an arbitrary third-party host via a crafted PASV response.
Users are recommended to upgrade to version 2.4.69, which fixes this issue.
