critical Nessus Plugin ID 94574

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3123-1 advisory.

 It was discovered that curl incorrectly reused client certificates when built with NSS. A remote attacker could possibly use this issue to hijack the authentication of a TLS connection. (CVE-2016-7141)

 Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain strings. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-7167)

 It was discovered that curl incorrectly handled storing cookies. A remote attacker could possibly use this issue to inject cookies for arbitrary domains in the cookie jar. (CVE-2016-8615)

 It was discovered that curl incorrect handled case when comparing user names and passwords. A remote attacker with knowledge of a case-insensitive version of the correct password could possibly use this issue to cause a connection to be reused. (CVE-2016-8616)

 It was discovered that curl incorrect handled memory when encoding to base64. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-8617)

 It was discovered that curl incorrect handled memory when preparing formatted output. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-8618)

 It was discovered that curl incorrect handled memory when performing Kerberos authentication. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-8619)

 Lut Nguyn discovered that curl incorrectly handled parsing globs. A remote 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 16.04 LTS and Ubuntu 16.10. (CVE-2016-8620)

 Lut Nguyn discovered that curl incorrectly handled converting dates. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service. (CVE-2016-8621)

 It was discovered that curl incorrectly handled URL percent-encoding decoding. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-8622)

 It was discovered that curl incorrectly handled shared cookies. A remote server could possibly obtain incorrect cookies or other sensitive information. (CVE-2016-8623)

 Fernando Muoz discovered that curl incorrect parsed certain URLs. A remote attacker could possibly use this issue to trick curl into connecting to a different host. (CVE-2016-8624)

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
