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