USN-5402-1: OpenSSL vulnerabilities

Related Vulnerabilities: CVE-2022-1292   CVE-2022-1343   CVE-2022-1434   CVE-2022-1473  

Several security issues were fixed in OpenSSL.

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)

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)
