    Package        : screen
    Vulnerability  : programming error
    Problem-Type   : local(remote)
    Debian-specific: no
    CVE ID         : CVE-2006-4573
    Debian Bug     : 395225 395999
    "cstone" and Rich Felker discovered that specially crafted UTF-8 sequences
    may lead an out of bands memory write when displayed inside the screen
    terminal multiplexer, allowing denial of service and potentially the
    execution of arbitrary code.
    For the stable distribution (sarge) this problem has been fixed in
    version 4.0.2-4.1sarge1. Due to technical problems with the security
    buildd infrastructure this update lacks a build for the Sun Sparc
    architecture. It will be released as soon as the problems are resolved.
    For the unstable distribution (sid) this problem has been fixed in
    version 4.0.3-0.1.
    We recommend that you upgrade your screen package.
