Subject: [SECURITY] [DSA 295-1] New pptpd packages fix remote root exploit
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
- --------------------------------------------------------------------------
Debian Security Advisory DSA 295-1 security@...ian.org
http://www.debian.org/security/ Martin Schulze
April 30th, 2003 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : pptpd
Vulnerability : buffer overflow
Problem-Type : remote
Debian-specific: no
CVE Id : CAN-2003-0213
Timo Sirainen discovered a vulnerability in pptpd, a Point to Point
Tunneling Server, which implements PPTP-over-IPSEC and is commonly
used to create Virtual Private Networks (VPN). By specifying a small
packet length an attacker is able to overflow a buffer and execute
code under the user id that runs pptpd, probably root. An exploit for
this problem is already circulating.
For the stable distribution (woody) this problem has been fixed in
version 1.1.2-1.4.
For the old stable distribution (potato) this problem has been
fixed in version 1.0.0-4.2.
For the unstable distribution (sid) this problem has been fixed in
version 1.1.4-0.b3.2.
We recommend that you upgrade your pptpd package immediately.
