Service interruption via PostScript interpreter out-of-bounds write
Published Mar 20, 2025 · Updated Oct 6, 2025
Out-of-bounds array write in Xpdf 4.05 and earlier allows local users to interrupt processing through a malformed PDF file. The PostScript function interpreter incorrectly checks for integer overflow before an array write, allowing the write to exceed the array bounds. Processing the triggering document is the required gate; the record does not disclose whether interruption occurs through a hang or crash, and it reports no data access or code execution.
