[ASA-201711-33] curl: information disclosure
Arch Linux Security Advisory ASA-201711-33 ========================================== Severity: Medium Date : 2017-11-30 CVE-ID : CVE-2017-8817 Package : curl Type : information disclosure Remote : Yes Link : Summary ======= The package curl before version 7.57.0-1 is vulnerable to information disclosure. Resolution ========== Upgrade to 7.57.0-1. # pacman -Syu "curl>=7.57.0-1" The problem has been fixed upstream in version 7.57.0. Workaround ========== None. Description =========== A read out of bounds flaw has been found in the FTP wildcard function of libcurl >= 7.21.0 and < 7.57.0. 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 will continue 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. Impact ====== A remote attacker is able to crash the application or possibly disclose sensitive information on the affected host. References ==========
