Two security issues were fixed in Lynx.
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 “man 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)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
