CVE-2004-0414 is a high-severity flaw (CVSS 10.0) affecting cvs, openpkg, propack. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16, does not properly handle malformed "Entry" lines, which prevents a NULL terminator from being used and may lead to a denial of service (crash), modification of critical program data, or arbitrary code execution.

Why this priority

  • Critical severity
  • EPSS top 10%: very likely to be exploited
