apache2 vulnerabilities
Details

USN-6729-1 fixed several vulnerabilities in Apache. This update provides the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Original advisory details:

Orange Tsai discovered that the Apache HTTP Server incorrectly handled validating certain input. A remote attacker could possibly use this issue to perform HTTP request splitting attacks. (CVE-2023-38709)

Keran Mu and Jianjun Chen discovered that the Apache HTTP Server incorrectly handled validating certain input. A remote attacker could possibly use this issue to perform HTTP request splitting attacks. (CVE-2024-24795)

Bartek Nowotarski discovered that the Apache HTTP Server HTTP/2 module incorrectly handled endless continuation frames. A remote attacker could possibly use this issue to cause the server to consume resources, leading to a denial of service. This issue was addressed only in Ubuntu 18.04 LTS. (CVE-2024-27316)
