CVE-2026-125251

FFmpeg through 9.0.2 VVC Decoder Heap Out-of-Bounds Write via refs.c

FFmpeg through 9.0.2 contains an integer overflow vulnerability in the VVC decoder alloc_frame() function in libavcodec/vvc/refs.c that undersizes the reference picture list allocation on 32-bit builds. Attackers can supply a crafted VVC (H.266) file with a very large number of NAL units per access unit to trigger heap out-of-bounds writes and corrupt memory.

FFmpeg through 9.0.2 Heap Corruption via libaribcaption ASS Error Cleanup

FFmpeg through 9.0.2 contains an out-of-bounds read and invalid free vulnerability in aribcaption_trans_ass_subtitle() in libavcodec/libaribcaption.c that frees subtitle rectangles using region_count instead of num_rects. Attackers can supply crafted ARIB captions whose later region exceeds the 8 KiB AVBPrint limit, triggering cleanup that frees out-of-bounds pointers and corrupts the heap.

FFmpeg through 9.0.2 Heap Buffer Overflow in EXR Encoder RLE Path

FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in libavcodec/exrenc.c that allows attackers to corrupt heap memory when encode_scanline_rle() processes frames taller than the encoder height. Attackers can supply crafted input whose resolution grows mid-stream, transcoded to OpenEXR with RLE compression, to write pointers past the scanline array and crash the application.

FFmpeg 9.0 through 9.0.2 Integer Overflow via FFV1 Vulkan Encoder Remap Buffer

FFmpeg 9.0 through 9.0.2 contains an integer overflow vulnerability in libavcodec/ffv1enc_vulkan.c that undersizes the float remap GPU buffer for large frames. Attackers can supply large GBRPF32 or GBRAPF32 images or videos that, when transcoded to FFV1 with the Vulkan encoder, trigger out-of-bounds GPU memory writes causing crashes or memory corruption.

FFmpeg through 9.0.2 ProRes prores_aw Heap Out-of-Bounds Read in Interlaced Encoding

FFmpeg through 9.0.2 contains a heap out-of-bounds read vulnerability in libavcodec/proresenc_anatoliy.c that occurs when the prores_aw encoder processes interlaced, odd-height frames. Attackers can supply odd-height video that causes subimage_with_fill_template() to fill padding rows from memory before the fill_y buffer, leaking heap contents into the encoded output.

Apache OFBiz: renderLink compiles link parameters as FreeMarker source

Improper Neutralization of Special Elements Used in a Template Engine ('Server-Side Template Injection') in MacroScreenRenderer in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only the two view permissions of a control-servlet webapp (e.g. CATALOG_VIEW and OFBTOOLS_VIEW on /catalog, held by OFBiz's own shipped order-entry clerk role) to execute arbitrary operating system commands as the OFBiz service account with a single GET request, by placing an apostrophe followed by FreeMarker expression source in a screen link parameter value, because renderLink concatenates link parameter values verbatim between apostrophes into an unquoted, unescaped template-source string that is compiled and evaluated at render time, allowing the injected expression to reach the allow-listed FlexibleStringExpander.expandString call and, through a runtime-assembled Groovy interpolation, unsandboxed code execution. Users are recommended to upgrade to version 24.09.08, which fixes this issue.

Apache OFBiz: REST API authentication bypassed by default when the auth attribute is omitted from a .rest.xml operation

Incorrect default value in the REST API framework's .rest.xml definition parser (ModelApiReader) in Apache OFBiz through 24.09.07 on all platforms allows a remote, unauthenticated attacker to invoke a REST API operation without providing valid credentials via a .rest.xml resource or operation definition that omits the auth attribute, which ModelApiReader incorrectly resolves to false instead of the true default declared by rest-api.xsd. Users are recommended to upgrade to version 24.09.08, which fixes this issue.
