What is CVE-2024-47543?
CVE-2024-47543 is a medium-severity memory corruption vulnerability in Gstreamer Gstreamer, published on 11 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
GStreamer is a library for constructing graphs of media-handling components. An OOB-read vulnerability has been discovered in qtdemux_parse_container function within qtdemux.c. In the parent function qtdemux_parse_node, the value of length is not well checked. So, if length is big enough, it causes the pointer end to point beyond the boundaries of buffer. Subsequently, in the qtdemux_parse_container function, the while loop can trigger an OOB-read, accessing memory beyond the bounds of buf. This vulnerability can result in reading up to 4GB of process memory or potentially causing a segmentation fault (SEGV) when accessing invalid memory. This vulnerability is fixed in 1.24.10.
Weakness: CWE-125
