From: Junio C Hamano <email@example.com> To: firstname.lastname@example.org Cc: Linux Kernel <email@example.com>, firstname.lastname@example.org Subject: [Announce] Git v2.26.2 and others Date: Mon, 20 Apr 2020 11:02:55 -0700 Message-ID: <email@example.com> (raw) Today, the Git project is releasing the following Git versions: v2.26.2, v2.25.4, v2.24.3, v2.23.3, v2.22.4, v2.21.3, v2.20.4, v2.19.5, v2.18.4, and v2.17.5. These releases address the security issue CVE-2020-11008, which is similar to the recently addressed CVE-2020-5260. Users of the affected maintenance tracks are urged to upgrade. The tarballs are found at: https://www.kernel.org/pub/software/scm/git/ The following public repositories all have a copy of the 'v2.26.2' and other tags: url = https://kernel.googlesource.com/pub/scm/git/git url = git://repo.or.cz/alt-git.git url = https://github.com/gitster/git Attached below is the release notes for 2.17.5; all the newer maintenance tracks listed at the beginning of this message are updated with the same fix, so I won't repeat them here. Thanks. -------------------------------------------------- Git v2.17.5 Release Notes ========================= This release is to address a security issue: CVE-2020-11008 Fixes since v2.17.4 ------------------- * With a crafted URL that contains a newline or empty host, or lacks a scheme, the credential helper machinery can be fooled into providing credential information that is not appropriate for the protocol in use and host being contacted. Unlike the vulnerability CVE-2020-5260 fixed in v2.17.4, the credentials are not for a host of the attacker's choosing; instead, they are for some unspecified host (based on how the configured credential helper handles an absent "host" parameter). The attack has been made impossible by refusing to work with under-specified credential patterns. Credit for finding the vulnerability goes to Carlo Arenas.
