Ubuntu 14.04 LTS : curl vulnerabilities (USN-2591-1)

critical Nessus Plugin ID 83182

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2591-1 advisory.

 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 Bck 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 Bck 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
