Package        : ntp
Vulnerability  : buffer overflows
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2009-0159 CVE-2009-1252
CERT advisory  : VU#853097
Debian Bug     : 525373

Several remote vulnerabilities have been discovered in NTP, the Network
Time Protocol reference implementation. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2009-0159

    A buffer overflow in ntpq allow a remote NTP server to create a
    denial of service attack or to execute arbitrary code via a crafted
    response.

CVE-2009-1252

    A buffer overflow in ntpd allows a remote attacker to create a
    denial of service attack or to execute arbitrary code when the
    autokey functionality is enabled.

For the old stable distribution (etch), these problems have been fixed in
version 4.2.2.p4+dfsg-2etch3.

For the stable distribution (lenny), these problems have been fixed in
version 4.2.4p4+dfsg-8lenny2.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your ntp package.
