Doc Text:
A flaw was found in speex. An out-of-bounds write vulnerability exists due to improper buffer length handling when decoding byte streams into external memory buffers. A remote attacker could exploit this flaw by streaming specially crafted audio data into an affected application, triggering memory corruption. This issue primarily leads to application crashes, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-10-26 22:31:47 UTC 
Speex (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.
