Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Records: veraPDF parser (Maven org.verapdf:parser) versions 1.30.2 and from 1.31.1 up to 1.31.23 are affected. A remote attacker who gets a validator to process a crafted PDF, with a malicious CMap stream used as a font encoding or ToUnicode map, can exhaust memory or CPU and cause denial of service. Upgrade to version 1.30.2 or 1.31.23. The source gives few details on workarounds.
