PYSEC-2026-2801 Out-of-bounds Write in OpenCV

An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV 4.1.0 corresponds with OpenCV-Python 4.1.0.25. A specially crafted XML file can cause a buffer overflow, resulting in multiple heap corruptions and potential code execution. An...

PYSEC-2026-2807 Improper Restriction of Operations within the Bounds of a Memory Buffer in OpenCV

In modules/imgcodecs/src/grfmtpxm.cpp, the length of buffer AutoBuffer src is small than expected, which will cause copy buffer overflow later. If the image is from remote, may lead to remote code execution or denial of service. This affects OpenCV 3.3 corresponding to OpenCV-Python 3.3.0.9 and...

PYSEC-2026-2823 Improper Restriction of Operations within the Bounds of a Memory Buffer in OpenCV

OpenCV 3.3.1 corresponding with opencv-python and opencv-contrib-python 3.3.1.11 has a Buffer Overflow in the cv::PxMDecoder::readData function in grfmtpxm.cpp, because an incorrect size value is used...

CVE-2026-58471

A flaw was found in GNU Wget. A remote attacker can exploit a heap buffer overflow vulnerability in the convertfname function. This occurs when processing a server-supplied filename that requires character set conversion, leading to memory corruption due to incorrect buffer reallocation. This can...

GHSA-8F95-V3JQ-CJ86 pymonocypher: Potential heap buffer overflow on nb_blocks in argon2i_32 when provided buffer is too small

Impact The argon2i32 implementation does not check the nbblocks size. If the caller does not provide a sufficiently large buffer based on the API contract, then argon2i32 will write past the end of the buffer and possibly corrupt the heap. Patches Fixed in 4.0.2.8, which now verifies that nbblock...
