Summary: curl vulnerabilities

Details: Paras Sethia discovered that curl could incorrectly re-use NTLM HTTP credentials when subsequently connecting to the same host over HTTP. (CVE-2015-3143) Hanno Böck discovered that curl incorrectly handled zero-length host names. If a user or automated system were tricked into using a specially crafted host name, an attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-3144) Hanno Böck discovered that curl incorrectly handled cookie path elements. If a user or automated system were tricked into parsing a specially crafted cookie, an attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-3145) Isaac Boukris discovered that when using Negotiate authenticated connections, curl could incorrectly authenticate the entire connection and not just specific HTTP requests. (CVE-2015-3148) Yehezkel Horowitz and Oren Souroujon discovered that curl sent HTTP headers both to servers and proxies by default, contrary to expectations. This issue only affected Ubuntu 14.10 and Ubuntu 15.04. (CVE-2015-3153)
