cURL/libcurl 7.x < 7.47.0 Multiple Vulnerabilities

Versions of cURL and libcurl prior to 7.47.0 are affected by multiple vulnerabilities :

• A flaw exists that allows traversing outside of a restricted path. The issue is due to the program not properly sanitizing colon characters, specifically path traversal style attacks (e.g. ‘…/’) supplied via file names. With a specially crafted file name, a context-dependent attacker can write arbitrary files. (CVE-2016-0754)
• A flaw exists in the ‘ConnectionExists()’ function in ‘lib/url.c’ that is triggered as credentials are not properly compared in proxy NTLM authentication. This may allow a remote attacker to reuse connections. (CVE-2016-0755)
