CURL-CVE-2017-8817
No affected components available
libcurl contains a read out of bounds flaw in the FTP wildcard function.
libcurl's FTP wildcard matching feature, which is enabled with the
CURLOPT_WILDCARDMATCH option can use a built-in wildcard function or a user
provided one. The built-in wildcard function has a flaw that makes it not
detect the end of the pattern string if it ends with an open bracket ([) but
instead it continues reading the heap beyond the end of the URL buffer that
holds the wildcard.
For applications that use HTTP(S) URLs, allow libcurl to handle redirects and have FTP wildcards enabled, this flaw can be triggered by malicious servers that can redirect clients to a URL using such a wildcard pattern.
