Published: 03 May 2024
Summary
CVE-2023-37327 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Gstreamer Gstreamer. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 9.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
GStreamer contains an integer overflow vulnerability during the parsing of FLAC audio files that can lead to remote code execution. The flaw, tracked as CVE-2023-37327 and originally ZDI-CAN-20775, stems from insufficient validation of user-supplied data, allowing an overflow to occur before a buffer is allocated. Affected installations of the GStreamer multimedia framework are exposed when processing malformed FLAC content, and the issue carries a CVSS 3.1 score of 8.8.
Remote attackers can exploit the vulnerability without authentication by supplying a specially crafted FLAC file to any application that uses the vulnerable GStreamer library. Successful exploitation grants arbitrary code execution in the context of the affected process, with attack vectors depending on how the library is integrated into media-handling workflows.
Public advisories from the GStreamer project and Zero Day Initiative, along with distribution notices such as those from Fedora, provide further details on the flaw and available updates. The associated EPSS score has remained low, with a current value of 0.0534 and a peak of 0.0609.

more
on the implementation. The specific flaw exists within the parsing of FLAC audio files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20775.
