Security C code scanner for misuse of format strings
PScan is a C source code security scanner, which looks for misuse of libc functions which use varargs and printf-style formatting operators. In many situations these can cause security vulnerabilities in the application if it runs with privileges setugid, or listening to a network socket, etc.
An example of the kind of situation pscan looks for is the following
variable = “s”; /* or malicious user input / sprintfbuffer, variable; / BAD! */
