Package : dhcpcd
Vulnerability : out-of-bound memory access
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2005-1848

"infamous42md" discovered that dhcpcd, a DHCP client for automatically configuring IPv4 networking, can be tricked into reading past the end of the supplied DHCP buffer which could lead to the daemon crashing.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 1.3.22pl4-21sarge1.

For the unstable distribution (sid) this problem has been fixed in version 1.3.22pl4-22.

We recommend that you upgrade your dhcpcd package.
