-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2019.0477 A vulnerability in python-gnupg has been addressed 15 February 2019 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: python-gnupg Publisher: Debian Operating System: Debian GNU/Linux 8 Windows UNIX variants (UNIX, Linux, OSX) Impact/Access: Access Confidential Data -- Existing Account Resolution: Patch/Upgrade CVE Names: CVE-2019-6690 Original Bulletin: https://lists.debian.org/debian-lts-announce/2019/02/msg00021.html Comment: This advisory references vulnerabilities in products which run on platforms other than Debian. It is recommended that administrators running python-gnupg check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- Package : python-gnupg Version : 0.3.6-1+deb8u1 CVE ID : CVE-2019-6690 Alexander Kjall and Stig Palmquist discovered a vulnerability in python-gnupg, a wrapper around GNU Privacy Guard. It was possible to inject data through the passphrase property of the gnupg.GPG.encrypt() and gnupg.GPG.decrypt() functions when symmetric encryption is used. The supplied passphrase is not validated for newlines, and the library passes --passphrase-fd=0 to the gpg executable, which expects the passphrase on the first line of stdin, and the ciphertext to be decrypted or plaintext to be encrypted on subsequent lines. By supplying a passphrase containing a newline an attacker can control/modify the ciphertext/plaintext being decrypted/encrypted. For Debian 8 "Jessie", this problem has been fixed in version 0.3.6-1+deb8u1. We recommend that you upgrade your python-gnupg packages.
