Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-1642-1)
Summary:	The remote host is missing an update for the 'lynx-cur' package(s) announced via the USN-1642-1 advisory.
Description:	Summary: The remote host is missing an update for the 'lynx-cur' package(s) announced via the USN-1642-1 advisory. Vulnerability Insight: Dan Rosenberg discovered a heap-based buffer overflow in Lynx. If a user were tricked into opening a specially crafted page, a remote attacker could cause a denial of service via application crash, or possibly execute arbitrary code as the user invoking the program. This issue only affected Ubuntu 10.04 LTS. (CVE-2010-2810) It was discovered that Lynx did not properly verify that an HTTPS certificate was signed by a trusted certificate authority. This could allow an attacker to perform a 'machine-in-the-middle' (MITM) attack which would make the user believe their connection is secure, but is actually being monitored. This update changes the behavior of Lynx such that self-signed certificates no longer validate. Users requiring the previous behavior can use the 'FORCE_SSL_PROMPT' option in lynx.cfg. (CVE-2012-5821) Affected Software/OS: 'lynx-cur' package(s) on Ubuntu 10.04, Ubuntu 11.10, Ubuntu 12.04, Ubuntu 12.10. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
