GStreamer H.266 Codec Parser Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the parsing of decoding units. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28839.
A flaw was found in GStreamer. A remote attacker can exploit this vulnerability by providing specially crafted H.266 codec data during the parsing of decoding units. This issue arises from insufficient validation of the length of user-supplied data before it is copied to a fixed-length stack-based buffer. Successful exploitation can lead to a stack-based buffer overflow, allowing for arbitrary code execution in the context of the current process.
Отчет
This is an IMPORTANT vulnerability affecting the GStreamer H.266 codec parser. The flaw allows remote attackers to execute arbitrary code by providing specially crafted H.266 media content. Exploitation requires user interaction with applications that process untrusted H.266 streams using GStreamer.
Меры по смягчению последствий
To reduce the risk of exploitation, avoid processing untrusted H.266 media content with applications that use the GStreamer framework. Restricting the sources of H.266 content to trusted origins is recommended.
