========================================================================== Ubuntu Security Notice USN-5328-1 March 15, 2022
openssl, openssl1.0 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS
Summary:
OpenSSL could be made to stop responding if it opened a specially crafted certificate.
Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools - openssl1.0: Secure Socket Layer (SSL) cryptographic library and tools
Details:
Tavis Ormandy discovered that OpenSSL incorrectly parsed certain certificates. A remote attacker could possibly use this issue to cause OpenSSH to stop responding, resulting in a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.10: libssl1.1 1.1.1l-1ubuntu1.2
Ubuntu 20.04 LTS: libssl1.1 1.1.1f-1ubuntu2.12
Ubuntu 18.04 LTS: libssl1.0.0 1.0.2n-1ubuntu5.8 libssl1.1 1.1.1-1ubuntu2.1~18.04.15
After a standard system update you need to reboot your computer to make all the necessary changes.
