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.
