cURL/libcURL TFTP URL Parsing Overflow
Remote / Network Access Input Manipulation
Loss of Integrity Upgrade
Exploit Unknown Vendor Verified

- 漏洞描述

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.

- 解决方案

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 # ./configure --disable-tftp && make

- 漏洞讨论

cURL and libcURL are prone to a buffer-overflow vulnerability. This issue is due to a failure in the library to perform proper bounds checks on user-supplied data before using it in a finite-sized buffer.

The issue occurs when the URL parser handles an excessively long URL string with a TFTP protocol prefix 'tftp://'.


An attacker can exploit this issue to crash the affected library, effectively denying service. Arbitrary code execution may also be possible, which may facilitate a compromise of the underlying system.
