ArchLinux: 201806-1: git: multiple issues
Summary
- CVE-2018-11233 (information disclosure)
A security issue has been found in git before 2.17.1, where the code
that sanify-check paths in is_ntfs_dotgit() could have been tricked
into reading random pieces of memory.
- CVE-2018-11235 (arbitrary code execution)
A security issue has been found in git before 2.17.1. With a crafted
.gitmodules file, a malicious project can execute an arbitrary script
on a machine that runs "git clone --recurse-submodules" because
submodule "names" are obtained from this file, and then appended to
$GIT_DIR/modules, leading to directory traversal with "../" in a name.
Finally, post-checkout hooks from a submodule are executed, bypassing
the intended design in which hooks are not obtained from a remote
server.
Resolution
Upgrade to 2.17.1-1.
# pacman -Syu "git>=2.17.1-1"
The problems have been fixed upstream in version 2.17.1.
