Struktur: >> Libde265 >> 1.0.4 Security Vulnerabilities
libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.20, a crafted H.265 bitstream can cause an out-of-bounds array write in `decoder_context::process_reference_picture_set()` (`libde265/decctx.cc:1376`). The root cause is a missing aggregate bound check on predicted short-term reference picture set entries. Individual list sizes are validated, but the combined count after predicted RPS construction can exceed the 16-entry `PocStFoll` array, writing at index 16. Version 1.0.20 patches the issue.

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in `de265_image_get_buffer()` (`libde265/image.cc:128`). The overflow wraps the plane allocation size to a small value (~1 KB), but the subsequent `fill_image()` call computes the real size using `size_t`, writing ~4 GB into the undersized heap buffer. Version 1.1.0 patches the issue.

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.17, a malformed H.265 PPS NAL unit causes a segmentation fault in pic_parameter_set::set_derived_values(). This issue has been patched in version 1.0.17.

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.17, a crafted HEVC bitstream causes an out-of-bounds heap write confirmed by AddressSanitizer. The trigger is a stale ctb_info.log2unitSize after an SPS change where PicWidthInCtbsY and PicHeightInCtbsY stay constant but Log2CtbSizeY changes, causing set_SliceHeaderIndex to index past the allocated image metadata array and write 2 bytes past the end of a heap allocation. This issue has been patched in version 1.0.17.
