CVE-2016-1979

Use-after-free vulnerability in the PK11_ImportDERPrivateKeyInfoAndReturnKey function in Mozilla Network Security Services (NSS) before 3.21.1, as used in Mozilla Firefox before 45.0, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted key data with DER encoding.

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, CVE-2016-2802).

These are all security issues fixed in the MozillaFirefox-50.1.0-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the MozillaThunderbird-45.5.1-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the libfreebl3-3.26.2-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the firefox-esr-128.5.1-1.1 package on the GA media of openSUSE Tumbleweed.

Christian Holler, Tyson Smith, and Phil Ringalda discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-2805, CVE-2016-2807)

Hanno Böck discovered that calculations with mp_div and mp_exptmod in NSS produce incorrect results in some circumstances, resulting in cryptographic weaknesses. (CVE-2016-1938)

A use-after-free was discovered in ssl3_HandleECDHServerKeyExchange in NSS. A remote attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-1978)

A use-after-free was discovered in PK11_ImportDERPrivateKeyInfoAndReturnKey in NSS. A remote attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-1979)
