Forensics Bugs (#2 rifitui)

rifitui is a tool to recover Windows recycle bins.

   int currrecoff;
  int recordsize;

 ...

   pread( info2_file, fourbytes, 4, 0x0C );
  recordsize = bah_to_i( fourbytes, 4 );

   record = malloc( recordsize );

 ...

   while (eof == 0) {
    res = pread( info2_file, record, recordsize, currrecoff );
    if (res < recordsize) {
      eof = 1;
    } else {
      filename = record + 0x04;
      index = bah_to_i( record+0x108, 4 );
      drive = bah_to_i( record+0x10C, 4 );

      deltime = win_time_to_unix( record+0x110 );
      deltm = localtime( &deltime );
      year = deltm->tm_year + 1900;
      mon = deltm->tm_mon + 1;
      sprintf( ascdeltime, "%02d/%02d/%02d %02d:%02d:%02d", mon, deltm->tm_mday, year, deltm->tm_hour, deltm->tm_min, deltm->tm_sec );

      filesize = bah_to_i( record+0x118, 4 );

      printf( "%d%s%s%s%d%s%s%s%d\n", index, delim, ascdeltime, delim, drive, delim, filename, delim, filesize );
    }
    currrecoff = currrecoff + recordsize;

It's not a big bug, but file offsets should probably be 64bit off_t and not int types. There is potential for integer overflows and other issues.

C++ Memory Corruption (std::string) - part 4

  Summary This is the next part of the C++ memory corruption series*. In this post, we'll look at corrupting the std:string object in Linux and see what exploitation primitives we can gain. * https://blog.infosectcbr.com.au/2020/08/c-memory-corruption-part-1.html * https://blog.infosectcbr.com.au/2022/01/c-memory-corruption-stdvector-part-2.html  *  https://blog.infosectcbr.com.au/2022/03/c-memory-corruption-stdlist-part-3.html Author: Dr Silvio Cesare Introduction C++ is a common language for memory corruption. However, there is much more literature on exploiting C programs and little on C++ programs. C++ presents new classes, objects, and data structures which can all be effectively used for building exploitation primitives. In this post, we'll look at corrupting the std::string class and see what specific primitives we can obtain. std::string We note that the object stored in memory for a basic string consists firstly of the backing pointer to the string contents.

Pointer Compression in V8

Syed Faraz Abrar @farazsth98   Summary In this blog post, I will provide some details on how the Chromium developers implemented pointer compression in V8. I will also talk about what this means from an exploit development perspective. Introduction I’ve been an intern at InfoSect for the past couple of weeks now, and in this time, I’ve had to do a bunch of security related research into both V8 and Spidermonkey. One of the things that I spent a short amount of my time on was pointer compression in V8. I hadn’t heard of the term at all until Bruno Keith ( @bkth_ ) mentioned it on twitter some time in December last year. The V8 developers also made a blog post to celebrate V8 v8.0 where they mentioned that implementing pointer compression had allowed them to save up to 40% in usage of heap memory! That’s a big improvement, so let’s take a look at what pointer compression is and what it means from an exploit developer’s perspective. Disclaimer This is not intended to
