HP Security Bulletin HPSBHF03544 1 - Potential security vulnerabilities in cURL and libcurl have been addressed with HPE iMC PLAT and other HP and H3C products using Comware 7. The vulnerabilities could be exploited remotely resulting in unauthorized access. Revision 1 of this advisory.
85b2d81dc1b3f872228664d35268d8bbb970c56095b755f549519a9b80b7f991Red Hat Security Advisory 2015-2159-06 - The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit. A flaw was found in the way the libcurl library performed the duplication of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's duplicate could cause the application to crash or disclose a portion of its memory.

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.

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.
