CVE-2009-2957

A buffer overflow in TFTP processing may enable arbitrary code execution to attackers which are permitted to use the TFTP service.

CVE-2009-2958

Malicious TFTP clients may crash dnsmasq, leading to denial of service.

The old stable distribution is not affected by these problems.

For the stable distribution (lenny), these problems have been fixed in version 2.45-1+lenny1.

For the unstable distribution (sid), these problems have been fixed in version 2.50-1.

We recommend that you upgrade your dnsmasq packages.");
