    https://www.kernel.org/pub/software/scm/git/

The following public repositories all have a copy of the 'v2.48.1' tag, as well as the tags for older maintenance tracks listed above.

  url = https://kernel.googlesource.com/pub/scm/git/git
  url = git://repo.or.cz/alt-git.git
  url = https://github.com/gitster/git

These releases make Git refuse to accept URLs that contain control sequences to address CVE-2024-50349 and CVE-2024-52006.

 - CVE-2024-50349:

   Printing unsanitized URLs when asking for credentials made the
   user susceptible to crafted URLs (e.g. in recursive clones) that
   mislead the user into typing in passwords for trusted sites that
   would then be sent to untrusted sites instead.

 - CVE-2024-52006

   Git may pass on Carriage Returns via the credential protocol to
   credential helpers which use line-reading functions that
   interpret said Carriage Returns as line endings, even though Git
   did not intend that.

Huge credit goes to Dscho who led and coordinated the fixes for this set of releases.
