Severity: normal
Exploitable: local
Date: 2021-04-30
Bug(s): #774678
ID: 202104-01

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: dev-vcs/git
Vulnerable: < 2.26.3
Unaffected: >= 2.26.3
Architectures: All supported architectures


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

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:
