CVE-2007-3961
Description
From CVE.org
Off-by-one error in the fsp_readdir_r function in fsplib.c in fsplib before 0.9 allows remote attackers to cause a denial of service via a directory entry whose length is exactly MAXNAMELEN, which prevents a terminating null byte from being added.
Statement
Red Hat does not consider a user assisted client crash such as this to be a security flaw.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Instability
This weakness will generally lead to undefined behavior and therefore crashes. In the case of overflows involving loop index variables, the likelihood of infinite loops is also high.
Integrity
Technical Impact: Modify Memory
If the value in question is important to data (as opposed to flow), simple data corruption has occurred. Also, if the wrap around results in other conditions such as buffer overflows, further memory corruption may occur.
Confidentiality,Availability,Access Control
Technical Impact: Execute Unauthorized Code or Commands; Bypass Protection Mechanism
This weakness can sometimes trigger buffer overflows which can be used to execute arbitrary code. This is usually outside the scope of a program's implicit security policy.
