Synopsis ========
A vulnerability has been found in Git that could allow a remote attacker to execute arbitrary code.
Background ==========
Git is a distributed version control system designed.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-vcs/git < 2.26.3 >= 2.26.3
Description ===========
It was discovered that Git could be fooled into running remote code during a clone on case-insensitive file systems with support for symbolic links, if Git is configured globally to apply delay-capable clean/smudge filters (such as Git LFS).
Impact ======
A remote attacker could entice a user to clone a specially crafted repository, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Git users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-vcs/git-2.26.3"
References ==========
[ 1 ] CVE-2021-21300 https://nvd.nist.gov/vuln/detail/CVE-2021-21300
