26 May 2022
Several security issues were fixed in OpenSSL.
Releases
o Ubuntu 16.04 ESM
Packages
o openssl - Secure Socket Layer (SSL) cryptographic library and tools
Details
USN-5402-1 fixed several vulnerabilities in OpenSSL. This update provides
the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
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 )
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 )
Update instructions
The problem can be corrected by updating your system to the following package
versions:
Ubuntu 16.04
