The remote Ubuntu 24.04 LTS. host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6729-3 advisory.
USN-6729-1 fixed vulnerabilities in Apache HTTP Server. This update provides the corresponding updates for Ubuntu 24.04 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. (CVE-2024-27316)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
