Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-34903)
The 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.
2) OS Command Injection (CVE-ID: CVE-2015-20107)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the mailcap module, which does not escape characters into commands discovered in the system mailcap file. A remote unauthenticated attacker can pass specially crafted data to the applications that call mailcap.findmatch with untrusted input and execute arbitrary OS commands on the target system.
