Hi, You are receiving an AlmaLinux Security update email because you subscribed to receive errata notifications from AlmaLinux. AlmaLinux: 10 Type: Security Severity: Important Release date: 2026-04-24 Summary: The OpenJDK 25 packages provide the OpenJDK 25 Java Runtime Environment and the OpenJDK 25 Java Software Development Kit. Security Fix(es): * JDK: Enhance crypto algorithm support (CVE-2026-22007) * JDK: Improved Arena allocations (CVE-2026-22008) * JDK: Improve Kerberos credentialing (CVE-2026-22013) * JDK: Enhance Path Factories Redux (CVE-2026-22016) * JDK: Enhance Zip file reading (CVE-2026-22018) * JDK: Enhance certificate chain validation (CVE-2026-22021) * JDK: Updating FreeType 2.14.1 (CVE-2026-23865) * JDK: Enhance TLS connection handling (CVE-2026-34282) * JDK: Enhance key generation (CVE-2026-34268) This release also updates a number of third-party libraries included in the JDK. The libraries themselves are affected by the following CVEs, but this is not a statement that the JDK itself is affected: * giflib: Denial of Service via buffer overflow in EGifGCBToExtension (CVE-2026-26740) * libpng: Information disclosure and denial of service via out-of-bounds read/write in Neon palette expansion (CVE-2026-33636) * libpng: Arbitrary code execution due to use-after-free vulnerability (CVE-2026-33416) Bug Fix(es): * When copying files, OpenJDK 25 prefers to use the copy_file_range native function for performance reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 25 releases, a response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is rectified in this release. (AlmaLinux-169939, AlmaLinux-169937) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
