Description Josh Bressers 2005-12-08 06:51:04 EST
+++ 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.'
Comment 1 Ivana Varekova 2005-12-08 09:54:24 EST
fc3 version (curl-7.12.3-5.fc3) and fc4 version (curl-7.13.1-4.fc4) are fixed
(devel version is fixed too - bug 175191 - curl-7.15.1-1 ).
