CVE-2005-0953
Race condition in bzip2 1.0.2 and earlier allows local users to modify
permissions of arbitrary files via a hard link attack on a file while
it is being decompressed, whose permissions are changed by bzip2 after
the decompression is complete.

CVE-2005-1260
bzip2 allows remote attackers to cause a denial of service (hard drive
consumption) via a crafted bzip2 file that causes an infinite loop
(a.k.a 'decompression bomb').");
