security advisorycriticalSlackwareSlackware 15.0: 2024-136-02 Critical: Git Local Clone Code Execution
New git packages are available for Slackware 15.0 and -current to fix security issues. . -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] git (SSA:2024-136-02) New git packages are available for Slackware 15.0 and -current to fix security issues. Here are the details from the Slackware 15.0 ChangeLog: +--------------------------+ patches/packages/git-2.39.4-i586-1_slack15.0.txz: Upgraded. This update fixes security issues: Recursive clones on case-insensitive filesystems that support symbolic links are susceptible to case confusion that can be exploited to execute just-cloned code during the clone operation. Repositories can be configured to execute arbitrary code during local clones. To address this, the ownership checks introduced in v2.30.3 are now extended to cover cloning local repositories. Local clones may end up hardlinking files into the target repository's object database when source and target repository reside on the same disk. If the source repository is owned by a different user, then those hardlinked files may be rewritten at any point in time by the untrusted user. When cloning a local source repository that contains symlinks via the filesystem, Git may create hardlinks to arbitrary user-readable files on the same filesystem as the target repository in the objects/ directory. It is supposed to be safe to clone untrusted repositories, even those unpacked from zip archives or tarballs originating from untrusted sources, but Git can be tricked to run arbitrary code as part of the clone.

security advisorymoderatesecurity fixSlackware 14.0+: 2023-046-02 Moderate: Git Data Exfiltration Risk
New git packages are available for Slackware 14.0, 14.1, 14.2, 15.0, and -current to fix security issues. . -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] git (SSA:2023-046-02) New git packages are available for Slackware 14.0, 14.1, 14.2, 15.0, and -current to fix security issues. 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".
