{"id":"CLSA-2026-1789565568","summary":"Fix CVE(s): CVE-2026-86421","details":"   * SECURITY UPDATE: memory leak in the MSL group handler\n     - debian/patches/CVE-2026-86421.patch: destroy the per-level DrawInfo in\n       the \u003c/group\u003e unwind of MSLEndElement. The unwind released the image,\n       the attributes and the image_info of every level it popped, but never\n       the DrawInfo that MSLPushImage clones for that level, so each nested\n       \u003cgroup\u003e element leaked one DrawInfo (coders/msl.c)\n     - debian/patches/CVE-2026-86421-1.patch: bound that unwind loop so a\n       stale group_info numImages count cannot drive msl_info-\u003en below zero.\n       This version predates upstream 8867bada, so the loop had no bound and\n       the DrawInfo destroy added above would otherwise widen the existing\n       out-of-bounds free by one pointer (coders/msl.c)\n     - debian/patches/CVE-2026-86421-2.patch: destroy the per-level DrawInfo\n       in MSLPopImage() too. MSLPopImage handles the \u003c/image\u003e pop outside a\n       group and is disjoint from the \u003c/group\u003e unwind patched above; this\n       version predates upstream 08278c7c (first released in 6.9.10-0), so\n       without it a crafted MSL document repeating \u003cimage\u003e...\u003c/image\u003e still\n       leaks one DrawInfo per pop (coders/msl.c)\n     -
