• Ubuntu 18.04 ESM

Packages

• openssl - Secure Socket Layer (SSL) cryptographic library and tools

Chancen and Daniel Fiala 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.

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04

• openssl - 1.1.1l-1ubuntu1.5

Ubuntu 20.04

• openssl - 1.1.1f-1ubuntu2.15

Ubuntu 18.04

• openssl - 1.1.1-1ubuntu2.1~18.04.19
