Description

This security bulletin contains information about 2 vulnerabilities.


1) Spoofing attack (CVE-ID: CVE-2018-12019)

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to conduct spoofing attack.

The vulnerability exists due to the signature verification routine interprets user ids as status/control messages and does not correctly keep track of the status of multiple signatures. A remote attacker can spoof arbitrary email signatures via public keys containing crafted primary user ids and gain access to potentially sensitive information.


2) Spoofing attack (CVE-ID: CVE-2018-12020)

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to conduct spoofing attack.

The vulnerability exists due to an input validation flaw in the processing of filenames when displaying the filename. A remote attacker can send a signed and encrypted email message that includes the specially crafted name of the original input file, spoof status messages and fake the verification status of a signed email message.
