Summary
openjdk-21 vulnerabilities
Details

Jinfeng Guo discovered that the Security component of OpenJDK 21 did not correctly handle certain representations of encoded strings. An unauthenticated remote attacker could possibly use this issue to modify files or leak sensitive information. (CVE-2025-53057)

Darius Bohni discovered that the JAXP component of OpenJDK 21 was vulnerable to a XML External Entity (XEE) attack. An unauthenticated remote attacker could possibly use this issue to modify files or leak sensitive information. (CVE-2025-53066)

Yakov Shafranovich discovered that the Libraries component of OpenJDK 21 contained an issue where certain Strings built with StringBuilder returned an incorrect result for String.equals() checks. An unauthenticated remote attacker could possibly use this issue to update, insert, or delete accessible data. (CVE-2025-61748)

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.
