Descriptions du CVE

gpgv in GnuPG before 1.4.2.1, when using unattended signature verification, returns a 0 exit code in certain cases even when the detached signature file does not carry a signature, which could cause programs that use gpgv to assume that the signature verification has succeeded. Note: this also occurs when running the equivalent command "gpg --verify".

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/16663/info GnuPG is affected by a detached signature verification-bypass vulnerability because it fails to properly notify scripts that an invalid detached signature was presented and that the verification process has failed. Exploiting this issue allows attackers to bypass the signature-verification process used in some automated scripts. Depending on the use of GnuPG, this may result in a false sense of security, the installation of malicious packages, the execution of attacker-supplied code, or other attacks. An example demonstrating this issue was provided: fortune >x.txt perl -e 'print "\xca"x"64"' >x.txt.sig gpgv x.txt.sig x.txt echo $? This creates a file as well as an obviously invalid detached signature file. The file is then successfully validated by 'gpgv', since the exit status is '0'.
