# CVE-2024-10573: Mpg123: buffer overflow when writing decoded pcm samples

Status: published. Published: 2024-10-31. Updated: 2026-11-05.

An out-of-bounds write flaw was found in mpg123 when handling crafted streams. When decoding PCM, the libmpg123 may write past the end of a heap-located buffer. Consequently, heap corruption may happen, and arbitrary code execution is not discarded. The complexity required to exploit this flaw is considered high as the payload must be validated by the MPEG decoder and the PCM synth before execution. Additionally, to successfully execute the attack, the user must scan through the stream, making web live stream content (such as web radios) a very unlikely attack vector.

## Remediation

- workaround: This vulnerability can be mitigated by using the --no-frankenstein option to the mpg123 application. (source: CNA: redhat)
