freerdp: FreeRDP: Arbitrary code execution via heap out-of-bounds write in RLE planar decode path

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A malicious RDP server can exploit a heap out-of-bounds write vulnerability in the planardecompressplanerle function. This vulnerability allows the server to write past the end of a temporary buffer, potentiall...

UBUNTU-CVE-2026-27809

psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.12.2, when a PSD file contains malformed RLE-compressed image data e.g. a literal run that extends past the expected row size, decoderle raises ValueError which propagated all the way to the user, crashin...

psd-tools 安全漏洞

psd-tools is an open-source Python package designed for reading Adobe Photoshop PSD files. Versions of psd-tools prior to 1.12.2 contained security vulnerabilities. These vulnerabilities occurred due to the lack of handling of ValueError exceptions when processing PSD files containing...

CVE-2026-27809 psd-tools: Compression module has unguarded zlib decompression, missing dimension validation, and hardening gaps

psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.12.2, when a PSD file contains malformed RLE-compressed image data e.g. a literal run that extends past the expected row size, decoderle raises ValueError which propagated all the way to the user, crashin...

CVE-2026-27809

psd-tools (Python) prior to v1.12.2 is vulnerable when parsing PSD files with malformed RLE-compressed image data: decode_rle() can raise ValueError that was not caught, causing psd.composite() and psd-tools export to crash. The fix in v1.12.2 wraps the decode_rle() call in a try/except so that t...

FreeRDP 缓冲区错误漏洞

FreeRDP is an open-source RDP protocol implementation developed by the FreeRDP team. Versions of FreeRDP prior to 3.23.0 contained a buffer error vulnerability. This vulnerability stemmed from the lack of boundary checks in the RLE plane decoding process, which could lead to out-of-bounds write...

CVE-2026-23530

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0,freerdpbitmapdecompressplanar does not validate nSrcWidth/nSrcHeight against planar-maxWidth/maxHeight before RLE decode. A malicious server can trigger a client‑side heap buffer overflow, causing a crash DoS...

CVE-2026-23530 FreeRDP has heap-buffer-overflow in planar_decompress_plane_rle

FreeRDP is a free implementation of the Remote Desktop Protocol.

CVE-2026-23530

FreeRDP (freerdp_bitmap_decompress_planar, and related paths in RDP handling) is affected by a client-side heap buffer overflow in versions prior to 3.21.0, triggered by insufficient validation of dimensions before RLE decode and other decode paths, leading to DoS and potential code‑execution ris...

PT-2026-3455

Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.21.0 Description FreeRDP is a free implementation of the Remote Desktop Protocol. The freerdp bitmap decompress planar function does not properly validate the nSrcWidth and nSrcHeight parameters against...

SUSE CVE-2025-59730

When decoding a frame for a SANM file ANIM v0 variant, the decoded data can be larger than the buffer allocated for it. Frames encoded with codec 48 can specify their resolution width x height. A buffer of appropriate size is allocated depending on the resolution. This codec can encode the frame...

SUSE CVE-2025-59731

When decoding an OpenEXR file that uses DWAA or DWAB compression, the specified raw length of run-length-encoded data is not checked when using it to calculate the output data. We read rlerawsize from the input file at 0, we decompress and decode into the buffer td-rlerawdata of size rlerawsize a...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the oldcodec48 process when decoding SANM frames using run-length encoding, as the decoded data may exceed the allocated buffer size. An attacker can cause memory corruption or potentially execute arbitrary code b...
