Subject Name:            zlib
Subject Summary:         zlib Compression Library
Subject Home:            http://www.info-zip.org/pub/infozip/zlib/
Subject Versions:        * <= 1.1.3

Vulnerability Id:        cert:VN-368819
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           denial of service, exposure of sensitive information,
                         arbitrary code execution

Description:
    According to a Zlib Security Advisory [5] and the original CERT
    Security Advisory [6] from Jeffrey P. Lanza, there is a bug in the
    Zlib compression library that may manifest itself as a vulnerability
    in programs that are linked with Zlib. This may allow an attacker to
    conduct a denial-of-service attack, gather information, or execute
    arbitrary code. The vulnerability results from a programming error
    that causes segments of dynamically allocated memory to be released
    more than once.
