Description: When determining tty, Sudo does not correctly parse the contents of /proc/[pid]/ stat, local attackers may use this method to overwrite any file on the file system, bypassing expected permissions or getting the root shell. Impact: Local attackers could exploit this issue to run arbitrary commands with root privileges. Sudo versions 1.8.6p7 through 1.8.20 are vulnerable. Mitigation: Updates are available.

Description: The TLS session cache in FreeRADIUS before 3.0.14 fails to reliably prevent resumption of an unauthenticated session, which allows remote attackers (such as malicious 802.1X supplicants) to bypass authentication via PEAP or TTLS. Impact: An attacker can exploit this issue to bypass the authentication mechanism and perform unauthorized actions. This may lead to further attacks. FreeRADIUS versions prior to 3.0.14 are vulnerable. Mitigation: Updates...

Description: The tcp_splice_read function in net/ipv4/tcp.c in the Linux kernel before 4.9.11 allows remote attackers to cause a denial of service (infinite loop and soft lockup) via vectors involving a TCP packet with the URG flag. Impact: Attackers can exploit this issue to cause the kernel to enter into an infinite loop which may cause denial-of-service conditions. Mitigation: Updates are available. Please see the references...

Description: On Juniper Networks EX Series Ethernet Switch, running affected Junos OS versions, has been discovered with a vulnerability in IPv6 processing that may allow a specially crafted IPv6 Neighbor Discovery (ND) packet destined to an EX Series Ethernet Switch to cause a slow memory leak. A malicious network-based packet flood of these crafted IPv6 NDP packets may eventually lead to resource exhaustion and a...

Description: All versions of Samba from 3.5.0 onward are vulnerable to a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it. Impact: Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the affected application. Failed exploits will result in denial-of-service conditions. Mitigation:...
