Detailsinfo

A vulnerability was found in GStreamer up to 1.24.9 and classified as critical. Affected by this issue is the function gst_opus_dec_parse_header of the file gstopusdec.c. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. CVE summarizes:

GStreamer is a library for constructing graphs of media-handling components. stack-buffer overflow has been detected in the gst_opus_dec_parse_header function within `gstopusdec.c'. The pos array is a stack-allocated buffer of size 64. If n_channels exceeds 64, the for loop will write beyond the boundaries of the pos array. The value written will always be GST_AUDIO_CHANNEL_POSITION_NONE. This bug allows to overwrite the EIP address allocated in the stack. This vulnerability is fixed in 1.24.10.

The advisory is available at securitylab.github.com. This vulnerability is handled as CVE-2024-47607 since 09/27/2024. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit.
