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...

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...
