| Descripción: | Summary:
The remote host is missing an update for the 'firefox, firefox-l10n, nspr, nss' package(s) announced via the MGASA-2016-0105 advisory.
Vulnerability Insight:
Updated nss and firefox packages fix security vulnerabilities:
Security researcher SkyLined reported a use-after-free issue in how audio is
handled through the Web Audio API during MediaStream playback through
interactions with the Web Audio API. This results in a potentially
exploitable crash (CVE-2015-4477).
Security researcher cgvwzq reported that it is possible to read cross-origin
URLs following a redirect if performance.getEntries() is used along with an
iframe to host a page. Navigating back in history through script, content is
pulled from the browser cache for the redirected location instead of going
to the original location. This is a same-origin policy violation and could
allow for data theft (CVE-2015-7207).
A heap-based buffer overflow flaw was found in the way NSS parsed certain
ASN.1 structures. An attacker could use this flaw to create a specially
crafted certificate which, when parsed by NSS, could cause it to crash, or
execute arbitrary code, using the permissions of the user running an
application compiled against the NSS library (CVE-2016-1950).
Mozilla developer Tim Taubert used the Address Sanitizer tool and software
fuzzing to discover a use-after-free vulnerability while processing DER
encoded keys in the Network Security Services (NSS) libraries. The
vulnerability overwrites the freed memory with zeroes (CVE-2016-1979).
Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox (CVE-2016-1952, CVE-2016-1954, CVE-2016-1957, CVE-2016-1958,
CVE-2016-1960, CVE-2016-1961, CVE-2016-1962, CVE-2016-1974, CVE-2016-1964,
CVE-2016-1965, CVE-2016-1966).
Multiple security flaws were found in the graphite2 font library shipped
with Firefox. A web page containing malicious content could cause Firefox
to crash or, potentially, execute arbitrary code with the privileges of the
user running Firefox (CVE-2016-1977, CVE-2016-2790, CVE-2016-2791,
CVE-2016-2792, CVE-2016-2793, CVE-2016-2794, CVE-2016-2795, CVE-2016-2796,
CVE-2016-2797, CVE-2016-2798, CVE-2016-2799, CVE-2016-2800, CVE-2016-2801,
