-Subject: Info-ZIP UnZip buffer overflow
-Bug-Debian: http://bugs.debian.org/776589
-
-By carefully crafting a corrupt ZIP archive with "extra fields" that
-purport to have compressed blocks larger than the corresponding
-uncompressed blocks in STORED no-compression mode, an attacker can
-trigger a heap overflow that can result in application crash or
-possibly have other unspecified impact.
-
-This patch ensures that when extra fields use STORED mode, the
-"compressed" and uncompressed block sizes match.
