Ubuntu Security Notice USN-3260-2

Posted May 11, 2017

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3260-2 - USN-3260-1 fixed vulnerabilities in Firefox. The update caused the date picker panel and form validation errors to close immediately on opening. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, obtain sensitive information, spoof the addressbar contents or other UI elements, escape the sandbox to read local files, conduct cross-site scripting attacks, cause a denial of service via application crash, or execute arbitrary code. A flaw was discovered in the DRBG number generation in NSS. If an attacker were able to perform a man-in-the-middle attack, this flaw could potentially be exploited to view sensitive information. Various other issues were also addressed.
