[arch-security] [ASA-201601-9] openssh: multiple issues

Arch Linux Security Advisory ASA-201601-9 ========================================= Severity: High Date : 2016-01-14 CVE-ID : CVE-2016-0777 CVE-2016-0778 Package : openssh Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package openssh before version 7.1p2-1 is vulnerable to multiple issues including information disclosure (including the client's private keys) and arbitrary code execution. Resolution ========== Upgrade to 7.1p2-1. # pacman -Syu "openssh>=7.1p2-1" The problems have been fixed upstream in version 7.1p2. Workaround ========== It is possible to mitigate this issue by setting the following option in the OpenSSH client's configuration file manually, either global (/etc/ssh/ssh_config) or user specific (~/.ssh/config): UseRoaming no The above directive should be placed in the Host * section of the configuration file to use this setting for all SSH servers the client connects to. You can also set the option via a command line argument when connecting to an SSH server: -o 'UseRoaming no' Using one of those configuration values mitigates the problems by disabling the roaming feature. Description =========== - CVE-2016-0777 (information disclosure) An information leak flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory (possibly including private SSH keys) of a successfully authenticated OpenSSH client. - CVE-2016-0778 (arbitrary code execution) A buffer overflow flaw was found in the way the OpenSSH client roaming feature was implemented that is leading to a file descriptor leak. A malicious server could potentially use this flaw to execute arbitrary code on a successfully authenticated OpenSSH client if that client used certain non-default configuration options (ProxyCommand, ForwardAgent or ForwardX11). Impact ====== A remote attacker is able to use a malicious server to leak client memory, including the client's private keys or, under certain non default circumstances, execute arbitrary code. Users with passphrase-less privates keys, especially in non interactive setups (automated jobs using ssh, scp, rsync+ssh etc.) are advised to update their keys if they have connected to an SSH server they don't fully trust.

[arch-security] openssh: workaround for critical vulnerability
by Levente Polyak 14 Jan '16

14 Jan '16

Summary ======= A critical client side SSH vulnerability has been discovered and a patched upstream version is released as 7.1p2. We strongly advise to use the following workaround until the upcoming release is rolled out in Arch Linux. This vulnerability is being tracked as CVE-2016-0777. Workaround ========== Add undocumented "UseRoaming no" to ssh_config or use "-oUseRoaming=no" work around the issue. References ========== https://lists.mindrot.org/pipermail/openssh-unix-dev/2016-January/034680.ht… https://www.marc.info/?l=openbsd-tech&m=145278077820529 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0777

Arch Linux Security Advisory ASA-201601-8 ========================================= Severity: Medium Date : 2016-01-13 CVE-ID : CVE-2015-7995 Package : libxslt Type : denial of service Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package libxslt before version 1.1.28-4 is vulnerable to denial of service. Resolution ========== Upgrade to 1.1.28-4. # pacman -Syu "libxslt>=1.1.28-4" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== A type confusion vulnerability was discovered in the xsltStylePreCompute() function of libxslt. A remote attacker could possibly exploit this flaw to cause an application using libxslt to crash by tricking the application into processing a specially crafted XSLT document. Impact ====== A remote attacker is able to create a specially crafted XSLT document that, when processed, is leading to an application crash resulting in denial of service. References ========== https://access.redhat.com/security/cve/CVE-2015-7995 https://git.gnome.org/browse/libxslt/commit/?id=7ca19df89 https://bugzilla.redhat.com/show_bug.cgi?id=1257962 https://bugs.archlinux.org/task/47681

Resolution ========== Upgrade to 6.10.0-1. # pacman -Syu "dhcpcd>=6.10.0-1" The problem has been fixed upstream in version 6.10.0. Workaround ========== None. Description =========== - CVE-2016-1503 (denial of service) An issue has been discovered that can lead to a heap overflow via malformed dhcp responses later in print_option (via dhcp_envoption1) due to incorrect option length values. - CVE-2016-1504 (denial of service) A malformed dhcp response can lead to an invalid read/crash leading to denial of service. Impact ====== A remote attacker is able to send specially crafted packets leading to application crash resulting in denial of service.
