ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker.

Incorrect HTTP Request header comparison in Squid HTTP Proxy 3.5.0.1 through 3.5.22, and 4.0.1 through 4.0.16 results in Collapsed Forwarding feature mistakenly identifying some private responses as being suitable for delivery to multiple clients.

Incorrect processing of responses to If-None-Modified HTTP conditional requests in Squid HTTP Proxy 3.1.10 through 3.1.23, 3.2.0.3 through 3.5.22, and 4.0.1 through 4.0.16 leads to client-specific Cookie data being leaked to other clients. Attack requests can easily be crafted by a client to probe a cache for this information.

An issue was discovered in eClinicalWorks Patient Portal 7.0 build 13. This is a reflected Cross Site Scripting vulnerability which affects the raceMasterList.jsp page within the Patient Portal. Inserted payload is rendered within the Patient Portal and the raceMasterList.jsp page does not require authentication. The vulnerability can be used to extract sensitive information or perform attacks against the user's browser. The vulnerability affects the raceMasterList.jsp page and the following parameter: race.

An issue was discovered in eClinicalWorks healow@work 8.0 build 8. This is a blind SQL injection within the EmployeePortalServlet, which can be exploited by un-authenticated users via an HTTP POST request and which can be used to dump database data out to a malicious server, using an out-of-band technique, such as select_loadfile(). The vulnerability affects the EmployeePortalServlet page and the following parameter: employer.

An exploitable stack-based buffer overflow vulnerability exists in the querying functionality of Aerospike Database Server 3.10.0.3. A specially crafted packet can cause a stack-based buffer overflow in the function as_sindex__simatch_list_by_set_binid resulting in remote code execution. An attacker can simply connect to the port to trigger this vulnerability.

An exploitable stack-based buffer overflow vulnerability exists in the querying functionality of Aerospike Database Server 3.10.0.3. A specially crafted packet can cause a stack-based buffer overflow in the function as_sindex__simatch_by_iname resulting in remote code execution. An attacker can simply connect to the port to trigger this vulnerability.

An exploitable out-of-bounds read vulnerability exists in the client message-parsing functionality of Aerospike Database Server 3.10.0.3. A specially crafted packet can cause an out-of-bounds read resulting in disclosure of memory within the process, the same vulnerability can also be used to trigger a denial of service. An attacker can simply connect to the port and send the packet to trigger this vulnerability.

An exploitable heap write out of bounds vulnerability exists in the decoding of BPG images in Libbpg library. A crafted BPG image decoded by libbpg can cause an integer underflow vulnerability causing an out of bounds heap write leading to remote code execution. This vulnerability can be triggered via attempting to decode a crafted BPG image using Libbpg.

Privilege escalation vulnerability in Lenovo Transition application used in Lenovo Yoga, Flex and Miix systems running Windows allows local users to execute code with elevated privileges.

CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix.

The gdImageCreate function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (system hang) via an oversized image.

Double free vulnerability in the gdImageWebPtr function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to have unspecified impact via large width and height values.

The dynamicGetbuf function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted TIFF image.

Characters from languages are such as Arabic, Hebrew are displayed from RTL (Right To Left) order in Opera 37.0.2192.105088 for Android, due to mishandling of several unicode characters such as U+FE70, U+0622, U+0623 etc and how they are rendered combined with (first strong character) such as an IP address or alphabet could lead to a spoofed URL. It was noticed that by placing neutral characters such as "/", "?" in filepath causes the URL to be flipped and displayed from Right To Left. However, in order for the URL to be spoofed the URL must begin with an IP address followed by neutral characters as omnibox considers IP address to be combination of punctuation and numbers and since LTR (Left To Right) direction is not properly enforced, this causes the entire URL to be treated and rendered from RTL (Right To Left). However, it doesn't have be an IP address, what matters is that first strong character (generally, alphabetic character) in the URL must be an RTL character.

VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check.

Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations.

Xen through 4.8.x allows local 64-bit x86 HVM guest OS users to gain privileges by leveraging mishandling of SYSCALL singlestep during emulation.
