This bug can cause lbzip2 to allocate huge amounts of memory (more then hundreds of gigabytes per thread). This case is not so rare, decompressing an average hard disk image will likely trigger it as there will probably be long runs of zeros (unallocated sectors). Even in average case memory allocation is way too high. This in my opinion makes lbzip2 unsuitable for a stable release.
This bug was recently fixed in upstream version 2.2 and the fix should really make into Wheezy. I am rising severity to serious. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
