Ubuntu 22.04 LTS : OpenSSL vulnerabilities (USN-5710-1)

high Nessus Plugin ID 166798

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5710-1 advisory.

 It was discovered that OpenSSL incorrectly handled certain X.509 Email Addresses. If a certificate authority were tricked into signing a specially-crafted certificate, a remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. The default compiler options for affected releases reduce the vulnerability to a denial of service. (CVE-2022-3602, CVE-2022-3786)

 It was discovered that OpenSSL incorrectly handled applications creating custom ciphers via the legacy EVP_CIPHER_meth_new() function. This issue could cause certain applications that mishandled values to the function to possibly end up with a NULL cipher and messages in plaintext. (CVE-2022-3358)

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.
