Descriptions

GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been detected in the parse_lrc function within gstsubparse.c. The parse_lrc function calls strchr() to find the character ']' in the string line. The pointer returned by this call is then passed to g_strdup(). However, if the string line does not contain the character ']', strchr() returns NULL, and a call to g_strdup(start + 1) leads to a null pointer dereference. This vulnerability is fixed in 1.24.10.

Multiple multiple vulnerabilities were discovered in plugins for the GStreamer media framework and its codecs and demuxers, which may result in denial of service or potentially the execution of arbitrary code if a malformed media file is opened.
