USN-5402-2: OpenSSL vulnerabilities
26 May 2022
Several security issues were fixed in OpenSSL.
o Ubuntu 16.04 ESM
o openssl - Secure Socket Layer (SSL) cryptographic library and tools
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 )
The problem can be corrected by updating your system to the following package
o libssl1.0.0 - 1.0.2g-1ubuntu4.20+esm3
Available with UA Infra or UA Desktop
After a standard system update you need to reboot your computer to make
all the necessary changes.
o USN-5402-1 : openssl, libssl1.0-dev, openssl1.0, libssl-doc, libssl1.0.0,
libssl-dev, libssl1.1, libssl3
