Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : OpenSSL vulnerabilities (USN-5402-1)

critical Nessus Plugin ID 160502

Language:

Synopsis

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

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5402-1 advisory.

 Elison Niven discovered that OpenSSL incorrectly handled the c_rehash script. A local attacker could possibly use this issue to execute arbitrary commands when c_rehash is run. (CVE-2022-1292)

 Raul Metsma discovered that OpenSSL incorrectly verified certain response signing certificates. A remote attacker could possibly use this issue to spoof certain response signing certificates. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-1343)

 Tom Colley discovered that OpenSSL used the incorrect MAC key in the RC4-MD5 ciphersuite. In non-default configurations were RC4-MD5 is enabled, a remote attacker could possibly use this issue to modify encrypted communications. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-1434)

 Aliaksei Levin discovered that OpenSSL incorrectly handled resources when decoding certificates and keys.
 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. (CVE-2022-1473)

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
