    Package : lynx-ssl
    Vulnerability : buffer overflow
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2005-3120

    Ulf Härnhammar discovered a buffer overflow in lynx, a text-mode
    browser for the WWW that can be remotely exploited. During the
    handling of Asian characters when connecting to an NNTP server lynx
    can be tricked to write past the boundary of a buffer which can lead
    to the execution of arbitrary code.

    For the old stable distribution (woody) this problem has been fixed in
    version 2.8.4.1b-3.2.

    For the stable distribution (sarge) this problem has been fixed in
    version 2.8.5-2sarge1 of lynx.

    For the unstable distribution (sid) this problem will be fixed soon.

    We recommend that you upgrade your lynx-ssl package.
