[SECURITY] [DSA-372-1] New netris packages fix buffer overflow
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 - -- Debian Security Advisory DSA 372-1 [EMAIL PROTECTED] http://www.debian.org/security/ Matt Zimmerman August 16th, 2003 http://www.debian.org/security/faq - -- Package: netris Vulnerability : buffer overflow Problem-Type : remote Debian-specific: no CVE Ids: CAN-2003-0685 Shaun Colley discovered a buffer overflow vulnerability in netris, a network version of a popular puzzle game. A netris client connecting to an untrusted netris server could be sent an unusually long data packet, which would be copied into a fixed-length buffer without bounds checking. This vulnerability could be exploited to gain the priviliges of the user running netris in client mode, if they connect to a hostile netris server. For the current stable distribution (woody) this problem has been fixed in version 0.5-4woody1. For the unstable distribution (sid) this problem is fixed in version 0.52-1. We recommend that you update your netris package. Upgrade Instructions - wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

[SECURITY] [DSA-373-1] New autorespond packages fix buffer overflow
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 - -- Debian Security Advisory DSA 373-1 [EMAIL PROTECTED] http://www.debian.org/security/ Matt Zimmerman August 16th, 2003 http://www.debian.org/security/faq - -- Package: autorespond Vulnerability : buffer overflow Problem-Type : remote Debian-specific: no CVE Ids: CAN-2003-0654 Christian Jaeger discovered a buffer overflow in autorespond, an email autoresponder used with qmail. This vulnerability could potentially be exploited by a remote attacker to gain the privileges of a user who has configured qmail to forward messages to autorespond. This vulnerability is currently not believed to be exploitable due to incidental limits on the length of the problematic input, but there may be situations in which these limits do not apply. For the stable distribution (woody) this problem has been fixed in version 2.0.2-2woody1. For the unstable distribution (sid) this problem will be fixed soon.
