From: Matthieu Herrb Subject: [update] png 1.6.51 To: tech@openbsd.org Date: Sat, 22 Nov 2025 10:49:48 +0100 Hi, This is for the embedded libpng in xenocara. The matching port update was sent to ports@. CVE-2025-64505 (CVSS 6.1, Moderate): Heap buffer over-read in png_do_quantize via malformed palette index. CVE-2025-64506 (CVSS 6.1, Moderate): Heap buffer over-read in png_write_image_8bit with 8-bit input and convert_to_8bit enabled. CVE-2025-64720 (CVSS 7.1, High): Out-of-bounds read in png_image_read_composite via palette premultiplication with PNG_FLAG_OPTIMIZE_ALPHA. CVE-2025-65018 (CVSS 7.1, High): Heap buffer overflow in png_combine_row triggered via png_image_finish_read when processing 16-bit interlaced PNGs with 8-bit output format. All vulnerabilities require user interaction (processing a malicious PNG file) and can result in information disclosure and/or denial of service. CVE-2025-65018 may enable arbitrary code execution via heap corruption in certain heap configurations. ok ? diff -urN -x CVS /usr/xenocara/lib/libpng/.appveyor.yml ./.appveyor.yml --- /usr/xenocara/lib/libpng/.appveyor.yml Wed Sep 17 16:44:36 2025 +++ ./.appveyor.yml Fri Nov 21 22:01:00 2025 @@ -2,8 +2,8 @@ branches: except: -
