Fully implemented.

Fortify SCA  

Can detect violations of this rule, but will return false positives if the initialization was done in another function.

Splint3.1.1  
GCC4.3.5 

Can detect some   violations of this rule when the -Wuninitialized flag is used.

Compass/ROSE  

Automatically detects simple violations of this rule, although it may return some false positives. It may not catch more complex violations, such as initialization within functions taking uninitialized variables as arguments. It does catch the second noncompliant code example, and can be extended to catch the first as well.

Coverity Prevent

5.0

NO_EFFECT

Can find cases of an uninitialized variable being used before it is initialized, although it cannot detect cases of uninitialized members of a struct. Because Coverity Prevent cannot discover all violations of this rule, further verification is necessary.

Related Vulnerabilities

CVE-2009-1888 results from a violation of this recommendation. Some versions of SAMBA (up to 3.3.5) call a function which takes in two potentially uninitialized variables involving access rights. An attacker can exploit this to bypass the access control list and gain access to protected files [xorl 2009].
