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...

Heimdal CVE-2017-11103 Man in the Middle Security Bypass Vulnerability
Description: Heimdal before 7.4 allows remote attackers to impersonate services with Orpheus’ Lyre attacks because it obtains service-principal names in a way that violates the Kerberos 5 protocol specification. In _krb5_extract_ticket() the KDC-REP service name must be obtained from the encrypted version stored in ‘enc_part’ instead of the unencrypted version stored in ‘ticket’. Use of the unencrypted version provides an opportunity for successful server impersonation...

Citrix NetScaler Gateway CVE-2017-7219 Heap Buffer Overflow Vulnerability
Description: A heap overflow vulnerability in Citrix NetScaler Gateway versions 10.1 before 135.8/135.12, 10.5 before 65.11, 11.0 before 70.12, and 11.1 before 52.13 allows a remote authenticated attacker to run arbitrary commands via unspecified vectors. Impact: Attackers can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. Mitigation: Updates are available....

GNU glibc CVE-2017-1000366 Local Memory Corruption Vulnerability
Description: glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and...

CVE-2017-9417 Broadpwn Bug of Android and iOS Devices
Description: Broadcom BCM43xx Wi-Fi chips allow remote attackers to execute arbitrary code via unspecified vectors, aka the “Broadpwn” issue. Impact: Broadcom Wi-Fi chips embedded in Android and iOS devices are vulnerable to a bug that allows an attacker to execute code on their devices, without any interaction needed from the user. Mitigation: Updates are available. Please check specific vendor advisory for more information. Reference URL’s:...

QEMU CVE-2017-9524 Denial of Service Vulnerability
Description: The qemu-nbd server in QEMU (aka Quick Emulator), when built with the Network Block Device (NBD) Server support, allows remote attackers to cause a denial of service (segmentation fault and server crash) by leveraging failure to ensure that all initialization occurs before talking to a client in the nbd_negotiate function. Impact: Attackers can exploit this issue to crash the QEMU instance, resulting in a...
