Race condition in the jas_stream_tmpfile function in libjasper/base/jas_stream.c in JasPer 1.900.1 allows local users to cause a denial of service (program exit) by creating the appropriate tmp.XXXXXXXXXX temporary file, which causes Jasper to exit. NOTE: this was originally reported as a symlink issue, but this was incorrect. NOTE: some vendors dispute the severity of this issue, but it satisfies CVE's requirements for inclusion.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
