NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
