Mandriva Linux Security Advisory 2015-219 - NTLM-authenticated connections could be wrongly reused for requests without any credentials set, leading to HTTP requests being sent over the connection authenticated as a different user. When parsing HTTP cookies, if the parsed cookie's path element consists of a single double-quote, libcurl would try to write to an invalid heap memory address. This could allow remote attackers to cause a denial of service. When doing HTTP requests using the Negotiate authentication method along with NTLM, the connection used would not be marked as authenticated, making it possible to reuse it and send requests for one user over the connection authenticated as a different user.

Ubuntu Security Notice 2591-1 - Paras Sethia discovered that curl could incorrectly re-use NTLM HTTP credentials when subsequently connecting to the same host over HTTP. Hanno B=C3=B6ck 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. Various other issues were also addressed.
