Stack-based buffer overflow in the h_handlepeer function in http.cpp in httpdx 1.4, and possibly 1.4.3, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP GET request.

Format string vulnerability in the h_readrequest function in http.c in httpdx Web Server 1.4 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via format string specifiers in the Host header.

Multiple integer overflows in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via a crafted image file, related to integer multiplication for memory allocation.

Buffer overflow in the jas_stream_printf function in libjasper/base/jas_stream.c in JasPer 1.900.1 might allow context-dependent attackers to have an unknown impact via vectors related to the mif_hdr_put function and use of vsprintf.

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.
