FKIE_CVE-2016-7167

Vulnerability from fkie_nvd - Published: 2016-10-07 14:59 - Updated: 2026-06-17 00:52
Summary
Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl before 7.50.3 allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.
