Libde265

Heap buffer overflow in libde265 prior to version 1.1.0 allows remote attackers to corrupt heap memory and likely achieve code execution by tricking a user into processing a crafted H.265 video stream. The flaw stems from a 32-bit signed integer overflow in plane allocation sizing that wraps to ~1 KB, after which fill_image() writes the true ~4 GB plane content into the undersized buffer. No public exploit identified at time of analysis, but the upstream commit (8a1b5cf) and GHSA-vv8h-932h-7r86 publicly document the exact overflow location.

Out-of-bounds write in libde265 prior to version 1.0.20 allows remote attackers to corrupt memory by tricking a user into processing a maliciously crafted H.265 bitstream. The flaw resides in the short-term reference picture set handling and can lead to denial of service or potential code execution in any application that links libde265 for HEVC decoding. No public exploit identified at time of analysis, though the upstream patch and commit-level root-cause disclosure provide a clear roadmap for exploit development.

Unbounded heap growth in libde265 prior to version 1.0.20 allows remote attackers to exhaust process memory by delivering a crafted H.265 bitstream, resulting in denial of service. The flaw in `decoder_context::read_slice_NAL()` (decctx.cc:481) unconditionally attaches slice segment headers to finished picture objects regardless of whether an active image unit exists; in continuous streaming contexts these headers are never freed, enabling attacker-controlled memory accumulation without bound. No active exploitation is confirmed (not listed in CISA KEV) and no public POC has been identified at time of analysis, but the network-accessible, no-privileges-required vector makes any application consuming untrusted H.265 content an exposure surface.

A malformed H.265 PPS (Picture Parameter Set) NAL unit in libde265 prior to version 1.0.17 triggers a segmentation fault in the pic_parameter_set::set_derived_values() function, causing denial of service. Any application using affected versions of libde265 to decode H.265 video streams is vulnerable to crash via specially crafted video files or streams. The vulnerability has been patched in version 1.0.17, and a GitHub security advisory documents the issue.

A remote code execution vulnerability in libde265 (CVSS 5.5). Remediation should follow standard vulnerability management procedures.
