——0DevilutionX 1.4.0 through 1.5.5 contains a heap buffer overflow vulnerability in the bundled libmpq libmpq__archive_dup routine when opening crafted MPQ archives. Attackers can supply an MPQ archive whose block table count exceeds its hash table count, causing memcpy to overflow the heap during startup and crash the game.14h CVE-2026-1167416.5 MED

——0Speex (libspeex) through 1.2.1 contains an out-of-bounds write vulnerability in speex_bits_read_whole_bytes() in libspeex/bits.c that mishandles length truncation for non-owned SpeexBits buffers. Attackers can stream crafted Speex data into buffers set up with speex_bits_init_buffer() or speex_bits_set_bit_buffer() to corrupt heap or stack memory and crash applications.17h CVE-2026-1165905.9 MED

——0snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. Prior to 1.1.10.9, Snappy.arrayCopy(Object src, int offset, int byteLength, Object dest, int destOffset) passes caller-supplied ranges to native memcpy without validating either array, allowing negative or oversized byteLength and offset values to read or write outside array bounds and crash the JVM. SnappyOutputStream.rawWrite and SnappyInputStream.rawRead, including their typed-array write and read methods, pass caller-controlled ranges through this primitive, and typed-array byte-size calculations can overflow int. This issue is fixed in version 1.1.10.9.17h CVE-2026-869716.5 MED
