Ubuntu 22.04 LTS / 23.04 / 23.10 : OpenSSL vulnerabilities (USN-6450-1)

high Nessus Plugin ID 183790

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6450-1 advisory.

 Tony Battersby discovered that OpenSSL incorrectly handled key and initialization vector (IV) lengths.
 This could lead to truncation issues and result in loss of confidentiality for some symmetric cipher modes. (CVE-2023-5363)

 Juerg Wullschleger discovered that OpenSSL incorrectly handled the AES-SIV cipher. This could lead to empty data entries being ignored, resulting in certain applications being misled. This issue only affected Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-2975)

 It was discovered that OpenSSL incorrectly handled checking excessively long DH keys or parameters. A remote attacker could possibly use this issue to cause OpenSSL to consume resources, leading to a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-3446, CVE-2023-3817)

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.

Solution

Update the affected libssl-dev, libssl3 and / or openssl packages.
