[Bug 446670] Re: dpkg-deb crashed with SIGSEGV in inflate()

[Raphaël Hertzog]

inflate() is not part of dpkg but of zlib. It might be the that the
input data was corrupted but zlib should not segfault and instead
provide a proper error. This is rather old though and I'm not sure
anyone can find something useful in here.

Requesting a newer retrace in case anyone else duplicates it.

** Tags added: apport-request-retrace

** Package changed: dpkg (Ubuntu) => zlib (Ubuntu)
