Reporter Ubuntu Security Notice (C) 2005-2019 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.

Description

Sam Varshavchik discovered several buffer overflows in the HTBoundary_put_block() function. By sending specially crafted HTTP multipart/byteranges MIME messages, a malicious HTTP server could trigger an out of bounds memory access in the libwww library, which causes the program that uses the library to crash.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
