Cisco AnyConnect DMG Install Script Privilege Escalation

Cisco AnyConnect Secure Mobility Client for OS X is affected by a vulnerability that allows local attackers to mount arbitrary DMG files at arbitrary mount points. By exploiting this vulnerability is is possible for the attacker to gain root privileges. Cisco reports that a similar issue also exists in Cisco AnyConnect Secure Mobility Client for Linux.

Debian Security Advisory 3365-1

Debian Linux Security Advisory 3365-1 – Multiple security issues have been found in Iceweasel, Debian’s version integer overflows, buffer overflows, use-after-frees and other implementation errors may lead to the execution of arbitrary code, information disclosure or denial of service.

Cisco Security Advisory 20150923-fhs

Cisco Security Advisory – Two vulnerabilities in the IPv6 first hop security feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. Cisco has released software updates that address these vulnerabilities. There are no workarounds to mitigate these vulnerabilities.

Cisco Security Advisory 20150923-sshpk

Cisco Security Advisory – A vulnerability in the SSH version 2 (SSHv2) protocol implementation of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to bypass user authentication. Successful exploitation could allow the attacker to log in with the privileges of the user or the privileges configured for the Virtual Teletype (VTY) line. Depending on the configuration of the user and of the vty line, the attacker may obtain administrative privileges on the system. The attacker cannot use this vulnerability to elevate privileges. The attacker must know a valid username configured for RSA-based user authentication and the public key configured for that user to exploit this vulnerability. This vulnerability affects only devices configured for public key authentication method, also known as RSA-based user authentication feature. Cisco has released software updates that address this vulnerability. Workarounds for this vulnerability are not available; however administrators could temporarily disable RSA-based user authentication to avoid exploitation.

Cisco Security Advisory 20150923-iosxe

Cisco Security Advisory – A vulnerability in the processing of IPv4 packets that require Network Address Translation (NAT) and Multiprotocol Label Switching (MPLS) services of Cisco IOS XE Software for Cisco ASR 1000 Series, Cisco ISR 4300 Series, Cisco ISR 4400 Series, and Cisco Cloud Services 1000v Series Routers could allow an unauthenticated, remote attacker to cause a reload of the affected device. The vulnerability is due to improper processing of IPv4 packets that require NAT and MPLS processing. An attacker could exploit this vulnerability by sending an IPv4 packet to be processed by a Cisco IOS XE device configured to perform NAT and MPLS services. A successful exploit could allow the attacker to cause a reload of the affected device. Cisco has released software updates that address these vulnerabilities. There are no workarounds to mitigate this vulnerability.
