Skia, as used in Google Chrome before 16.0.912.77, does not perform all required initialization of values, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Weakness

The software does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.

Affected Software

Name Vendor Start Version End Version
Chrome Google * *
Chromium-browser Ubuntu devel *
Chromium-browser Ubuntu lucid *
Chromium-browser Ubuntu maverick *
Chromium-browser Ubuntu natty *
Chromium-browser Ubuntu oneiric *
Chromium-browser Ubuntu upstream *

Potential Mitigations

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable’s type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
