  • Bijective BWT (7 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (113 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

  • Precomp: More Compression for your Compressed Files (3 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

Old Format, New Bug

Posted by Sachin Garg on 12th September 2005 | Permanent Link

Secunia Research has discovered a vulnerability in NOD32 Anti-Virus, which potentially can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in handling ARJ archives containing compressed files with overly long filename. This can be exploited to cause a heap-based buffer overflow when a specially crafted ARJ archive is scanned.

Successful exploitation may allow arbitrary code execution, but requires that archive scanning is enabled. Bug has been fixed.

More details available here.
