Debian Security Advisory DSA-1522-1 security@debian.org
http://www.debian.org/security/ Florian Weimer
March 17, 2008 http://www.debian.org/security/faq
- - ----------------------------------------------------------------------
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.
Upgrade instructions
