Description Adam Mariš 2015-11-16 15:21:21 UTC
A format string vulnerability was found in CmdKeywords function when processing \keywords command in tex file. When the user runs latex2rtf with malicious crafted tex file, an attacker can execute arbitrary code. The variable `keywords' in the function CmdKeywords may hold a malicious input string, which can be used as a format argument of vsnprintf.

Vulnerable code:

1789        char *keywords = getBraceParam();
...
1798    fprintRTF(keywords);
...

858    void fprintRTF(char *format, ...){
      ...
873    vsnprintf(buffer, 1024, format, apf);
      ...
