Linux kernel CVE-2017-11176 : mq_notify function Denial of Service Vulnerability

Description:  The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact. Impact: An attacker can exploit this issue to cause denial-of-service condition. Mitigation: Updates are available. Please check...

Linux Kernel CVE-2017-7346 Local Denial of Service Vulnerability

Description: The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.7 does not validate certain levels data, which allows local users to cause a denial of service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device. Impact: A local attacker can exploit this issue to cause a denial-of-service condition. Linux Kernel 4.10.7 and prior versions are vulnerable. Mitigation: Updates are available. Please...

Apache Log4j CVE-2017-5645 Remote Code Execution Vulnerability

Description: In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code. 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....

Apache Tomcat CVE-2017-5648 Information Disclosure Vulnerability

Description:  While investigating bug 60718, it was noticed that some calls to application listeners in Apache Tomcat 9.0.0.M1 to 9.0.0.M17, 8.5.0 to 8.5.11, 8.0.0.RC1 to 8.0.41, and 7.0.0 to 7.0.75 did not use the appropriate facade object. When running an untrusted application under a SecurityManager, it was therefore possible for that untrusted application to retain a reference to the request or response object and thereby...

Linux kernel CVE-2017-7487 : ‘net/ipx/af_ipx.c’ Use After Free Local Denial of Service Vulnerability

Description:  The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel through 4.11.1 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface. Impact: An attacker can exploit this issue to cause a local denial-of-service condition. Mitigation: Updates are available. Please check specific vendor advisory for...
