This vulnerability only affects users whith the msg-view-url option enabled (which is not the default). ftp://atualizacoes.conectiva.com.br/7.0/RPMS/ pico-4.44L-1U70_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/ pine-4.44L-1U70_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/ pilot-4.44L-1U70_1cl.i386.rpm Conectiva Vendor Advisory: http://www.linuxsecurity.com/advisories/other_advisory-1877.html +---------------------------------+ | rsync | ----------------------------// +---------------------------------+ In Debian Security Advisory DSA-106-1 we reported a exploitable problem in rsync. For details please see that advisory. Unfortunately the patch used to fix that problem broke rsync. This has been fixed in version 2.3.2-1.5 and we recommend you upgrade to that version immediately. Debian Intel IA-32 architecture: http://security.debian.org/dists/stable/updates/ main/binary-i386/rsync_2.3.2-1.5_i386.deb MD5 checksum: 41891f496f0b38b176de1bd3df04945c Debian Vendor Advisory: http://www.linuxsecurity.com/advisories/debian_advisory-1878.html +---------------------------------+ | FreeBSD Kernel | ----------------------------// +---------------------------------+ On vulnerable FreeBSD systems where procfs is mounted, unprivileged local users may be able to cause a kernel panic. A race condition existed where a file could be removed between calling fstatfs() and the point where the file is accessed causing the file descriptor to become invalid. This may allow unprivileged local users to cause a kernel panic. Currently only the procfs filesystem is known to be vulnerable. FreeBSD: fetch ftp://ftp.FreeBSD.org/pub/FreeBSD/ CERT/patches/SA-02:09/fstatfs.patch FreeBSD Vendor Advisory: http://www.linuxsecurity.com/advisories/freebsd_advisory-1879.html +---------------------------------+ | wmtv | ----------------------------// +---------------------------------+ Nicolas Boullis found some security problems in the wmtv package (a dockable video4linux TV player for windowmaker) which is distributed in Debian GNU/Linux 2.2. With the current version of wmtv, the configuration file is written back as the superuser, and without any further checks. A mailicious user might use that to damage important files. Debian Intel ia32 architecture: http://security.debian.org/dists/stable/updates/main/ binary-i386/wmtv_0.6.5-2potato2_i386.deb MD5 checksum: 270d8553f9d732d612154dd0927ceece Debian Vendor Advisory: http://www.linuxsecurity.com/advisories/debian_advisory-1880.html +---------------------------------+ | telnet | ----------------------------// +---------------------------------+ New telnet, telnet-server packages are available for Red Hat Linux 5.2, 5.2, 7.0 and 7.1. These packages fix a problem where buffer overflows can provide root access to local users. It is recommended that all users update to the fixed packages. Red Hat: 7.1 i386: ftp://updates.redhat.com/7.1/en/os/i386/ telnet-0.17-18.1.i386.rpm d4c6ea58c27504771887ada7f89646dd ftp://updates.redhat.com/7.1/en/os/i386/ telnet-server-0.17-18.1.i386.rpm 3165c07852274f4303c1acebde8ded06 Red Hat Vendor Advisory: http://www.linuxsecurity.com/advisories/redhat_advisory-1881.html ------------------------------------------------------------------------ Distributed by: Guardian Digital, Inc.
