  "details": "GNU patch is vulnerable to a NULL pointer dereference when processing a specially crafted unified-diff patch file. Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite() during patch processing.\nAn attacker can trigger this condition with a malicious patch file, causing the utility to crash and resulting in a denial of service.\n\n\n\nThis issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313",
