libssh2 through 1.11.1, fixed in commit 42e33d8, contains a pre-authentication heap buffer overflow vulnerability that allows a malicious SSH server to corrupt heap metadata in any connecting client by sending a packet with a packet length smaller than the cipher's block size during...

ImageMagick before 7.1.2-15 contains a heap-buffer-overflow read vulnerability in GetPixelIndex caused by OpenPixelCache updating image channel metadata before pixel cache memory allocation. Attackers can trigger memory and disk allocation failures to cause a heap-buffer-overflow read affecting a...

JLSEC-2026-944 ImageMagick has heap-buffer-overflow via signed integer overflow in WriteUHDRImage when writing UHDR images with large dimensions

WriteUHDRImage in coders/uhdr.c uses int arithmetic to compute the pixel buffer size. When image dimensions are large, the multiplication overflows 32-bit int, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of...

JLSEC-2026-919 imagemagick: heap-buffer overflow read in MNG magnification with alpha

Vulnerability Details When performing image magnification in ReadOneMNGIMage in coders/png.c, there is an issue around the handling of images with separate alpha channels. When loading an image with a color type that implies a separate alpha channel ie. jngcolortype = 12, we will load the alpha...

JLSEC-2026-925 ImageMagick (WriteBMPImage): 32-bit integer overflow when writing BMP scanline stride → heap buffer overflow

Summary A 32-bit integer overflow in the BMP encoder’s scanline-stride computation collapses bytesperline stride to a tiny value while the per-row writer still emits 3 × width bytes for 24-bpp images. The row base pointer advances using the overflowed stride, so the first row immediately writes...

JLSEC-2026-894

A heap-buffer-overflow flaw was found in ImageMagick’s PushShortPixel function of quantum-private.h file. This vulnerability is triggered when an attacker passes a specially crafted TIFF image file to ImageMagick for conversion, potentially leading to a denial of service...

php: ext/openssl: memory corruption in openssl_encrypt with AES-WRAP-PAD

A flaw was found in the OpenSSL extension of PHP. The AES-WRAP-PAD algorithm implementation uses the size of the plaintext length without accounting for the RFC 5649 expansion to allocate the output buffer for the AES key-wrap-with-padding operation. This may lead to an undersized memory allocati...
