cURL/libcURL 'curl_easy_unescape()' Heap Memory Corruption Vulnerability

Medium

Synopsis

The cURL program is a library and command-line tool for transferring data using various protocols, including HTTP, FTP, and LDAP. A vulnerable version of cURL was detected from the host.

Description

A heap-based buffer overflow flaw was found in the way libcurl unescaped URLs. A remote attacker could provide a specially-crafted URL that, when processed by an application using libcurl that handles untrusted URLs, would possibly cause it to crash or, potentially, execute arbitrary code.

Solution

Upgrade the affected packages; the next version of cURL that fixes the issue is cURL 7.31.0.
