Apache XML Security For Java vulnerable to Infinite Loop

  • Disclosed: 14.05.2022
  • Updated: 11.10.2026 13:19

Affected versions of xmlsec are subject to a denial of service vulnerability. Should a user check the signature of a message larger than 512 MB, the method expandSize(int newPos) of class org.apache.xml.security.utils.UnsyncByteArrayOutputStream goes in an endless loop. A remote attacker could use this flaw to supply crafted XML that would lead to a denial of service.
