Description Josh Bressers 2005-12-08 11:51:12 UTC

+++ This bug was initially created as a clone of Bug #175191 +++

'Stefan Esser has reported a vulnerability in cURL/libcURL, which has an unknown
impact.'

'The vulnerability is caused due to an off-by-one error when parsing an URL that
is longer than 256 bytes. By using a specially crafted URL, a two-byte overflow
is reportedly possible. This may be exploited to corrupt memory allocation
structures. The vulnerability is reportedly exploitable only via a direct
request to cURL and not via a redirect.'

'The vulnerability has been reported in version 7.15.0 and prior.'
