Package        : lsh-utils
Vulnerability  : buffer overflow, typo
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2003-0826 CAN-2005-0814
Debian Bug     : 211662

Several security relevant problems have been discovered in lsh, the
alternative secure shell v2 (SSH2) protocol server.  The Common
Vulnerabilities and Exposures project identifies the following
vulnerabilities:

CAN-2003-0826

    Bennett Todd discovered a heap buffer overflow in lshd which could
    lead to the execution of arbitrary code.

CAN-2005-0814

    Niels Möller discovered a denial of service condition in lshd.

For the stable distribution (woody) these problems have been fixed in
version 1.2.5-2woody3.

For the unstable distribution (sid) these problems have been fixed in
version 2.0.1-2.

We recommend that you upgrade your lsh-server package.
