Description

A remote overflow exists in cURL/libCURL. cURL/libcURL fails to boundary check resulting in a heap overflow. With a specially crafted request, an attacker can cause arbitrary code execution by redirecting cURL/libcURL to a TFTP URL that exceeds 512 bytes in length resulting in a loss of integrity.

Classification

Solution

Upgrade to version 7.15.3 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround: reconfigure and compile cURL to remove TFTP support
