Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
veraPDF PDF parser is a PDF parser for veraPDF. Prior to 1.30.2 and 1.31.23, veraPDF-parser contains a denial-of-service vulnerability in veraPDF-parser/src/main/java/org/verapdf/pd/font/cmap/CMapParser.java and veraPDF-parser/src/main/java/org/verapdf/parser/postscript/PSOperator.java, where a crafted Type 0 font /Encoding or /ToUnicode CMap stream can execute unbounded PostScript array allocation or a zero-increment for loop and exhaust validator memory or CPU. This issue is fixed in versions 1.30.2 and 1.31.23.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

veraPDF-parser version 1.30.2 or 1.31.23 (depending on your current release train)

  1. 1. Identify the current veraPDF-parser version in your project by checking your dependency management system (Maven pom.xml, Gradle build.gradle, or similar).
  2. 2. Determine which release train you are on: versions 1.30.x should upgrade to 1.30.2, and versions 1.31.x should upgrade to 1.31.23.
  3. 3. Update the veraPDF-parser dependency version in your build configuration to the appropriate fixed release: change the version to 1.30.2 if on the 1.30.x line, or to 1.31.23 if on the 1.31.x line.
  4. 4. Rebuild and test your application to verify the upgrade does not introduce regressions.
  5. 5. Ensure that any PDF processing pipelines handling untrusted PDF files with Type 0 fonts now handle the fixed parser correctly.
