[CLSA-2026:1777552532] Fix CVE(s): CVE-2025-64720, CVE-2025-65018
Type:
security
Severity:
Important
Release date:
2026-04-30 12:35:45 UTC
Description:
* No-source-change rebuild against libpng (>= 1.6.37-2+tuxcare.els2) to pick up the libpng security fixes for: - CVE-2025-64720: png_image_read_composite OOB read on palette images with PNG_FLAG_OPTIMIZE_ALPHA (libpng < 1.6.51). - CVE-2025-65018: png_image_finish_read heap buffer overflow on 16-bit interlaced PNGs with 8-bit output (libpng < 1.6.51). Both vulnerabilities live entirely in libpng (used in OpenJDK only via the system libpng linked into libsplashscreen / AWT image decoding via libsplashscreen --with-libpng=system); no OpenJDK source change is required. The fix is delivered by the libpng rebuild (build 69ef31c7922f4d8bf30fd637, libpng1.6 1.6.37-2+tuxcare.els2). Bumping the Build-Depends floor on libpng-dev guarantees the fixed headers/library are linked in this rebuild.
