Red Hat Security Advisory 2024-8425-03 - Red Hat OpenShift Container Platform release 4.15.37 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include denial of service and traversal vulnerabilities.
Good cyber security practices depend on trustworthy information sources about security vulnerabilities. This article offers guidance around who to trust for this information.In 1999, MITRE Corporation, a US Government-funded research and development company, realized the world needed a uniform standard for reporting and tracking software security bugs. MITRE worked with the IT industry to invent a concept called CVE, for Common Vulnerabilities and Exposures. The CVE concept caught on, and today, the industry acknowledges CVE as the universal standard for security vulnerability reporting.Softw

### Impact A path traversal vulnerability was discovered in go-git versions prior to `v5.11`. This vulnerability allows an attacker to create and amend files across the filesystem. In the worse case scenario, remote code execution could be achieved. Applications are only affected if they are using the [ChrootOS](https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#ChrootOS), which is the default when using "Plain" versions of Open and Clone funcs (e.g. PlainClone). Applications using [BoundOS](https://pkg.go.dev/github.com/go-git/go-billy/v5/osfs#BoundOS) or in-memory filesystems are not affected by this issue. This is a `go-git` implementation issue and does not affect the upstream `git` cli. ### Patches Users running versions of `go-git` from `v4` and above are recommended to upgrade to `v5.11` in order to mitigate this vulnerability. ### Workarounds In cases where a bump to the latest version of `go-git` is not possible in a timely manner, we recommend limiting its use to only t...
### Impact A denial of service (DoS) vulnerability was discovered in go-git versions prior to `v5.11`. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in `go-git` clients. Applications using only the in-memory filesystem supported by `go-git` are not affected by this vulnerability. This is a `go-git` implementation issue and does not affect the upstream `git` cli. ### Patches Users running versions of `go-git` from `v4` and above are recommended to upgrade to `v5.11` in order to mitigate this vulnerability. ### Workarounds In cases where a bump to the latest version of `go-git` is not possible, we recommend limiting its use to only trust-worthy Git servers. ## Credit Thanks to Ionut Lalu for responsibly disclosing this vulnerability to us. ### References - [GHSA-mw99-9chc-xw7r](https://github.com/go-git/go-git/security/advisories/GHSA-mw99-9chc-xw7r)
