Slackware 14.0+: 2023-046-02 Moderate: Git Data Exfiltration Risk

slackware
Calendar Grey February 15, 2023
Dist Slackware Esm H88
Updated git distributions are now accessible for Slackware 14.0 and newer to resolve security vulnerabilities that affect local clone efficiency.
New git packages are available for Slackware 14.0, 14.1, 14.2, 15.0, and -current to fix security issues

Summary

Here are the details from the Slackware 15.0 ChangeLog: patches/packages/git-2.35.7-i586-1_slack15.0.txz: Upgraded. This update fixes security issues: Using a specially-crafted repository, Git can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links (c.f., CVE-2022-39253), the objects directory itself may still be a symbolic link. These two may be combined to include arbitrary files based on known paths on the victim's filesystem within the malicious repository's working copy, allowing for data exfiltration in a similar manner as CVE-2022-39253. By feeding a crafted input to "git apply", a path outside the working tree can be overwritten as the user who is running "git apply".
