Affected Packages:

unzip

Vulnerable:

Security database references:

In Mitre's CVE dictionary: CVE-2008-0888.

More information:

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

For the stable distribution (etch), this problem has been fixed in version 5.52-9etch4.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your unzip package.

Fixed in:
