========================================================================== Ubuntu Security Notice USN-5402-1 May 04, 2022
openssl, openssl1.0 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 22.04 LTS – Ubuntu 21.10 – Ubuntu 20.04 LTS – Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in OpenSSL.
Software Description: – openssl: Secure Socket Layer (SSL) cryptographic library and tools – openssl1.0: Secure Socket Layer (SSL) cryptographic library and tools
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)
Raul Metsma discovered that OpenSSL incorrectly verified certain response signing certificates. A remote attacker could possibly use this issue to spoof certain response signing certificates. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-1343)
Tom Colley discovered that OpenSSL used the incorrect MAC key in the RC4-MD5 ciphersuite. In non-default configurations were RC4-MD5 is enabled, a remote attacker could possibly use this issue to modify encrypted communications. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-1434)
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 22.04 LTS: libssl3 3.0.2-0ubuntu1.1
Ubuntu 21.10: libssl1.1 1.1.1l-1ubuntu1.3
Ubuntu 20.04 LTS: libssl1.1 1.1.1f-1ubuntu2.13
Ubuntu 18.04 LTS: libssl1.0.0 1.0.2n-1ubuntu5.9 libssl1.1 1.1.1-1ubuntu2.1~18.04.17
