Package        : unzip
Vulnerability  : programming error
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2008-0888

Tavis Ormandy discovered that unzip, when processing specially crafted
ZIP archives, could pass invalid pointers to the C library's free
routine, potentially leading to arbitrary code execution
(CVE-2008-0888).

For the stable distribution (etch), this problem has been fixed in
version 5.52-9etch1.

For the old stable distribution (sarge), this problem has been fixed
in version 5.52-1sarge5.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your unzip package.
