Buffer overflow in curl earlier than 6.0-1.1, and curl-ssl earlier than 6.0-1.2, allows remote attackers to execute arbitrary commands by forcing a long error message to be generated.

Dispair 0.1 and 0.2 allows remote attackers to execute arbitrary shell commands via certain form fields.

Multiple off-by-one errors in the cURL library (libcurl) 7.11.2 through 7.15.0 allow local users to trigger a buffer overflow and cause a denial of service or bypass PHP security restrictions via certain URLs that (1) are malformed in a way that prevents a terminating null byte from being added to either a hostname or path buffer, or (2) contain a "?" separator in the hostname portion, which causes a "/" to be prepended to the resulting string.

Heap-based buffer overflow in cURL and libcURL 7.15.0 through 7.15.2 allows remote attackers to execute arbitrary commands via a TFTP URL (tftp://) with a valid hostname and a long path.
