CVE-2014-0050: Input Validation

First published: Thu Feb 06 2014(Updated: )

A flaw was found in Apache Commons FileUpload. Specially-crafted input could trigger a denial of service if the buffer used by the MultipartStream was not big enough. Tomcat 7 includes an embedded copy of Apache Commons FileUpload, so it was possible to craft a malformed Content-Type header for a multipart request which would cause Tomcat to enter an infinite loop. This has been corrected in Tomcat 7 via commit r1565169 [1]. It has been corrected in Apache Commons FileUpload via commit r1565143 [2]. No new releases have been made with the changes; Tomcat 7.0.51 (not yet released) will correct this flaw.
