Description Lubomir Kundrak 2007-08-20 11:30:09 EDT
Description of problem:

233     String filename = tag.GetFileName();
234     String sTmpSuffix = ".XXXXXX";
242     strcpy(sTempFile, filename.c_str());
243     strcat(sTempFile, sTmpSuffix.c_str());
245 #if ((defined(__GNUC__) && __GNUC__ >= 3  ) || !defined(HAVE_MKSTEMP))
246     // This section is for Windows folk && gcc 3.x folk
247     fstream tmpOut;
248     createFile(sTempFile, tmpOut);

When compiled with gcc 3 or higher, file with a predictable name is created.
This can possibly be explited to conduct a symlink attack and either leak
information or overwrite arbitrary file on behalf of user using the library
(though I a have not had a look at createFile(), maybe the only problem is two
programs using the temporary file concurently).

Additional info:

The CVE identifier for this issue had been requested.
