CVE-ID: CVE-2022-34903
CWE-ID:
CWE-347 - Improper Verification of Cryptographic Signature
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error in GnuPG, which allows signature spoofing via arbitrary injection into the status line. A remote attacker who controls the secret part of any signing-capable key or subkey in the victim's keyring, can take advantage of this flaw to provide a correctly-formed signature that some software, including gpgme, will accept to have validity and signer fingerprint chosen from the attacker.
MitigationUpdate the affected package gnupg to the latest version.
Vulnerable software versionsUbuntu: 14.04 - 16.04
gnupg (Ubuntu package): before 2.1.116u buntu2.1+esm1
