Summary
thunderbird vulnerabilities
Details

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)
