Categoría:	Ubuntu Local Security Checks
Título:	Ubuntu Update for lynx-cur USN-1642-1
Resumen:	Ubuntu Update for Linux kernel vulnerabilities USN-1642-1
Descripción:	Summary: Ubuntu Update for Linux kernel vulnerabilities USN-1642-1 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 '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) Affected Software/OS: lynx-cur on Ubuntu 12.10, Ubuntu 12.04 LTS, Ubuntu 11.10, Ubuntu 10.04 LTS Solution: Please Install the Updated Packages. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
