Arch Linux Security Advisory ASA-201801-11 ========================================== Severity: High Date : 2018-01-11 CVE-ID : CVE-2017-18021 Package : qtpass Type : private key recovery Remote : Yes Link : https://security.archlinux.org/AVG-576 Summary ======= The package qtpass before version 1.2.1-1 is vulnerable to private key recovery. Resolution ========== Upgrade to 1.2.1-1. # pacman -Syu "qtpass>=1.2.1-1" The problem has been fixed upstream in version 1.2.1. Workaround ========== Use pwgen for generating new passwords. Description =========== It was discovered that QtPass before 1.2.1, when using the built-in password generator, generates possibly predictable and enumerable passwords. This only applies to the QtPass GUI. The generator used libc's random(), seeded with srand(msecs), where msecs is not the msecs since 1970 (not that that'd be secure anyway), but rather the msecs since the last second. This means there are only 1000 different sequences of generated passwords. Impact ====== Passwords generated using QtPass can potentially be recovered by an attacker due to the use of a non-cryptographically secure random number generator with a predictable seed. It is recommend to change all passwords created by QtPass.
