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

• Severity: medium (CVSS 6.7 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2024-10-31 · updated 2026-06-17
• Weakness: CWE-787

Description

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.
