Slackware: 2018-152-01 Moderate: Git Submodule Path Exploit

New git packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix security issues. . -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] git (SSA:2018-152-01) New git packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, 14.2, and -current to fix security issues. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/git-2.14.4-i586-1_slack14.2.txz: Upgraded. This update fixes security issues: Submodule "names" come from the untrusted .gitmodules file, but we blindly append them to $GIT_DIR/modules to create our on-disk repo paths. This means you can do bad things by putting "../" into the name. We now enforce some rules for submodule names which will cause Git to ignore these malicious names (CVE-2018-11235). Credit for finding this vulnerability and the proof of concept from which the test script was adapted goes to Etienne Stalmans. It was possible to trick the code that sanity-checks paths on NTFS into reading random piece of memory (CVE-2018-11233). Credit for fixing for these bugs goes to Jeff King, Johannes Schindelin and others.
