Two vulnerabilities have been reported in W3C Libwww, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
1) A boundary error exists in the "HTBoundary_put_block()" function when processing multipart MIME data. This can be exploited to cause an illegal memory access past the end of the input buffer via specially crafted multipart MIME data.
Successful exploitation can potentially cause an application that uses Libwww to crash.
2) An error in the included Expat XML Parser library can be exploited to cause a crash.
