CVE-2021-28955
Arbitrary code execution due to an uncontrolled search path for the git binary
描述
### Impact The go language recently addressed a security issue in the way that binaries are found before being executed. Some operating systems like Windows persist to have the current directory being part of the default search path, and having priority over the system-wide path. This means that it's possible for a malicious user to craft for example a `git.bat` command, commit it and push it in a repository. Later when git-bug search for the git binary, this malicious executable can take priority and be executed. ### Who is impacted This issue happen on Windows and some other operating systems with a badly configured PATH. All version prior to 0.7.2 are vulnerable to this issue. ### Patches Version 0.7.2 fix this issue. Users should update as soon as possible. ### References More details about this issue can be found [here](https://blog.golang.org/path-security).
