ID CVE-2016-1947
Summary Mozilla Firefox 43.x mishandles attempts to connect to the Application Reputation service, which makes it easier for remote attackers to trigger an unintended download by leveraging the absence of reputation data.

CWE CWE-19
CAPEC
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • XML Nested Payloads
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. By nesting XML data and causing this data to be continuously self-referential, an attacker can cause the XML parser to consume more resources while processing, causing excessive memory consumption and CPU utilization. An attacker's goal is to leverage parser failure to his or her advantage. In most cases this type of an attack will result in a denial of service due to an application becoming unstable, freezing, or crash. However it may be possible to cause a crash resulting in arbitrary code execution, leading to a jump from the data plane to the control plane [R.230.1].
  • XML Oversized Payloads
    Applications often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. By supplying oversized payloads in input vectors that will be processed by the XML parser, an attacker can cause the XML parser to consume more resources while processing, causing excessive memory consumption and CPU utilization, and potentially cause execution of arbitrary code. An attacker's goal is to leverage parser failure to his or her advantage. In many cases this type of an attack will result in a denial of service due to an application becoming unstable, freezing, or crash. However it is possible to cause a crash resulting in arbitrary code execution, leading to a jump from the data plane to the control plane [R.231.1].
  • XML Client-Side Attack
    Client applications such as web browsers that process HTML data often need to transform data in and out of the XML format by using an XML parser. It may be possible for an attacker to inject data that may have an adverse effect on the XML parser when it is being processed. These adverse effects may include the parser crashing, consuming too much of a resource, executing too slowly, executing code supplied by an attacker, allowing usage of unintended system functionality, etc. An attacker's goal is to leverage parser failure to his or her advantage. In some cases it may be possible to jump from the data plane to the control plane via bad data being passed to an XML parser. [R.484.1]

    description USN-2880-1 fixed vulnerabilities in Firefox. This update introduced a regression which caused Firefox to crash on startup with some configurations. This update fixes the problem. We apologize for the inconvenience. Bob Clary, Christian Holler, Nils Ohlmeier, Gary Kwong, Jesse Ruderman, Carsten Book, Randell Jesup, Nicolas Pierron, Eric Rescorla, Tyson Smith, and Gabor Krizsanits discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2016-1930, CVE-2016-1931) Gustavo Grieco discovered an out-of-memory crash when loading GIF images in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could exploit this to cause a denial of service. (CVE-2016-1933) Aki Helin discovered a buffer overflow when rendering WebGL content in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2016-1935) It was discovered that a delay was missing when focusing the protocol handler dialog. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to conduct clickjacking attacks. (CVE-2016-1937) 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) Nicholas Hurley discovered that Firefox allows for control characters to be set in cookie names. An attacker could potentially exploit this to conduct cookie injection attacks on some web servers. (CVE-2016-1939) It was discovered that when certain invalid URLs are pasted in to the addressbar, the addressbar contents may be manipulated to show the location of arbitrary websites. An attacker could potentially exploit this to conduct URL spoofing attacks. (CVE-2016-1942) Ronald Crane discovered three vulnerabilities through code inspection. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2016-1944, CVE-2016-1945, CVE-2016-1946) Francois Marier discovered that Application Reputation lookups didn't work correctly, disabling warnings for potentially malicious downloads. An attacker could potentially exploit this by tricking a user in to downloading a malicious file. Other parts of the Safe Browsing feature were unaffected by this. (CVE-2016-1947). 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.
