Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 do not properly initialize data structures for the nsDOMSVGZoomEvent::mPreviousScale and nsDOMSVGZoomEvent::mNewScale functions, which allows remote attackers to obtain sensitive information from process memory via a crafted web site.

Severity, decoded
CVSS 3.1Exploitable over the network, with no privileges and user interaction, leading to full loss of confidentiality.
How the score is built
- Attack vectorAn attacker can reach it over the internet; no access to your network needed.Network
- Attack complexityNo special conditions are needed; the attack works reliably.Low
- Privileges requiredNo account or login is needed.None
- User interactionA user has to do something first, such as open a file or click a link.Required
- ScopeThe damage stays within the vulnerable component.Unchanged
- Confidentiality impactAn attacker can read all data the affected component holds, or the most sensitive parts of it.High
- Integrity impactData cannot be changed by the attacker.None
- Availability impactThe component keeps working normally.None
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:NAttackers are exploiting this in the wild.
At least one step needs hands-on work, which slows mass attacks.
A successful attack gives limited control over the affected software or limited access to its data.
Public exploits
None foundNo exploit in Exploit-DB or Metasploit, and no scanner template. That lowers, but doesn't remove, the chance of mass exploitation.
