Unspecified vulnerability in the browser engine in Mozilla Firefox ESR 38.x before 38.8 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The remote host is affected by the vulnerability described in GLSA-201701-15 (Mozilla Firefox, Thunderbird: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox and       Thunderbird. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process or cause a Denial of Service condition via       multiple vectors.
  Workaround :

    There is no known workaround at this time.

Versions of Mozilla Firefox ESR 4.x earlier than 45.1 are unpatched for the following vulnerabilities :

 - Multiple memory corruption issues exist that allow an attacker to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-2805, CVE-2016-2807)
 - Multiple flaws exist in that are triggered as user-supplied input is not properly validated.  These flaws may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. (CVE-2016-2806)
 - A flaw exists due to improper validation of user-supplied input when handling the 32-bit generation count of the underlying HashMap.  A context-dependent attacker can exploit this to cause a buffer overflow condition, resulting in a denial of service or the execution of arbitrary code. (CVE-2016-2808)
 - A heap buffer overflow condition exists in the Google Stagefright component due to improper validation of user-supplied input when handling CENC offsets and the sizes table.  A context-dependent attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-2814)

Versions of Mozilla Firefox ESR earlier than 38.8 are unpatched for the following vulnerabilities : 

 - Multiple memory corruption issues exist that allow an attacker to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-2805, CVE-2016-2807)
 - A flaw exists due to improper validation of user-supplied input when handling the 32-bit generation count of the underlying HashMap.  A context-dependent attacker can exploit this to cause a buffer overflow condition, resulting in a denial of service or the execution of arbitrary code. (CVE-2016-2808)
 - A heap buffer overflow condition exists in the Google Stagefright component due to improper validation of user-supplied input when handling CENC offsets and the sizes table.  A context-dependent attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-2814)

This update upgrades Thunderbird to version 38.8.0.

Security Fix(es) :

  - Two flaws were found in the processing of malformed web     content. A web page containing malicious content could     cause Thunderbird to crash or, potentially, execute     arbitrary code with the privileges of the user running     Thunderbird. (CVE-2016-2805, CVE-2016-2807)

  - MFSA 2016-47 (bsc#977386)

  - CVE-2016-2814: Buffer overflow in libstagefright with     CENC offsets - MFSA 2016-44 (bsc#977381)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Mozilla Firefox was updated to fix the following vulnerabilities (bsc#977333) :

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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 Bock 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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple security issues have been found in Icedove, Debian's version of the Mozilla Thunderbird mail client: Multiple memory safety errors may lead to the execution of arbitrary code or denial of service.

The security update for icedove did not build on armhf. This is resolved by this upload.

The text of the original DLA follows :

Multiple security issues have been found in Icedove, Debian's version of the Mozilla Thunderbird mail client. Multiple memory safety errors may lead to the execution of arbitrary code or denial of service.

For Debian 7 'Wheezy', this problem has been fixed in version 38.8.0-1~deb7u1.

We recommend that you upgrade your icedove packages.

The version of Firefox ESR installed on the remote Windows host is prior to 38.8. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist that allow an     attacker to corrupt memory, resulting in the execution     of arbitrary code. (CVE-2016-2805, CVE-2016-2807)

  - A flaw exists due to improper validation of     user-supplied input when handling the 32-bit generation     count of the underlying HashMap. A context-dependent     attacker can exploit this to cause a buffer overflow     condition, resulting in a denial of service or the     execution of arbitrary code. (CVE-2016-2808)

  - A heap buffer overflow condition exists in the Google     Stagefright component due to improper validation of     user-supplied input when handling CENC offsets and the     sizes table. A context-dependent attacker can exploit     this to cause a denial of service condition or the     execution of arbitrary code. (CVE-2016-2814)
