GStreamer is a library for constructing graphs of media-handling components. An OOB-Write has been detected in the function gst_parse_vorbis_setup_packet within vorbis_parse.c. The integer size is read from the input file without proper validation. As a result, size can exceed the fixed size of the pad->vorbis_mode_sizes array (which size is 256). When this happens, the for loop overwrites the entire pad structure with 0s and 1s, affecting adjacent memory as well. This OOB-write can overwrite up to 380 bytes of memory beyond the boundaries of the pad->vorbis_mode_sizes array. This vulnerability is fixed in 1.24.10.
This vulnerability has a CVSS score of 8.6, indicating a high severity level. The potential for exploitation is significant, and the risk to organizations includes possible memory corruption and application crashes.
Organizations should prioritize patching immediately. The vulnerability is present in all versions prior to 1.24.10 of GStreamer.
No public exploit has been confirmed for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) database. However, the absence of known exploits does not mitigate the immediate need for remediation.
Security teams should assess their current GStreamer implementations and implement necessary updates to ensure systems are protected against potential exploitation.
Vulnerability Details
CVE-2024-47615 is classified under CWE-787, which involves out-of-bounds write vulnerabilities. The CVSS version 4.0 score indicates a local attack vector with low complexity and no privileges required, meaning that an attacker could exploit this vulnerability without needing to authenticate.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of input size during the parsing of Vorbis packets. This lack of validation leads to the possibility of writing beyond the allocated buffer, resulting in memory corruption.
The attack vector is local, meaning the vulnerability can only be exploited by users that have access to the system. The attack complexity is low, as the exploitation does not require any specific conditions or user interaction. This increases the risk as it simplifies potential exploitation.
The impacts on confidentiality, integrity, and availability are all rated high, indicating that successful exploitation could lead to significant data breaches, corruption, or service disruptions.
Risk & Impact Analysis
Organizations utilizing GStreamer should assess the potential risk of this vulnerability. The consequences of exploitation could lead to unauthorized access to sensitive data and disruptions in service, directly impacting business operations.
The blast radius for this vulnerability is considerable due to the potential for widespread exploitation across affected systems. Given its high CVSS score, this vulnerability warrants immediate attention.
With an EPS score of 0.00084, the likelihood of exploitation appears low; however, the absence of known exploits does not reduce the urgency for patching. Organizations should address this issue in their priority patch cycle.

Affected Versions
All versions prior to 1.24.10 of GStreamer are affected by this vulnerability. Organizations using these versions should update to the latest version to mitigate the risks associated with this flaw.
Mitigation & Remediation
To mitigate this vulnerability, organizations should upgrade to GStreamer version 1.24.10 or later. For those unable to immediately apply the patch, consider implementing workarounds such as restricting access to the affected components and monitoring for unusual behavior.
Configuration hardening is essential to protect against potential exploitation. Organizations should also consider implementing network controls to limit exposure of vulnerable services.
Organizations should validate remediation through continuous penetration testing to ensure that all vulnerabilities have been adequately addressed.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual memory access patterns or application crashes. Additionally, look for behavioral anomalies that could indicate a successful exploitation attempt.
Network signatures should be established to identify any attempts to exploit this vulnerability, especially when dealing with media files processed by GStreamer.
