Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.\n\n## Affected\n\n- `go-git < 5.17.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `go-git 5.17.1`","depth":"sunlit","depthScore":15,"depthScoreParts":{"impact":15.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
