7.2
CVSS v3.1
Official Description
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.
Technical Analysis
CVE-2008-3521 requires local access, meaning attackers must already have a foothold on the target system.
