Details

USN-986-1 fixed vulnerabilities in bzip2. dpkg statically links against libbz2
and needed to be rebuilt to use the updated libbz2.

Original advisory details:

An integer overflow was discovered in bzip2. If a user or automated system
were tricked into decompressing a crafted bz2 file, an attacker could cause
bzip2 or any application linked against libbz2 to crash or possibly execute
code as the user running the program.
