A vulnerability was found in PHP where setting the environment variable PHPCLISERVERWORKERS to a large value leads to a heap buffer overflow.

An uncontrolled resource consumption vulnerability was discovered in HAProxy which could crash the service. This issue could allow an authenticated remote attacker to run a specially crafted malicious server in an OpenShift cluster. The biggest impact is to availability.

A flaw was found in haproxy. Anybody who can add a "set-cookie2 X=Y" header into the return path from their server/backend will kill haproxy in 2.2 (and onwards), resulting in a denial of service.

A flaw was found in ruby, where the date object was found to be vulnerable to a regular expression denial of service (ReDoS) during the parsing of dates. This flaw allows an attacker to hang a ruby application by providing a specially crafted date string. The highest threat to this vulnerability is system availability.

PostgreSQL is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements when the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, which could allow the attacker to view, add, modify or delete information in the back-end database.

A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include maxworkerprocesses=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virtext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape.

A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int("text"), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.frombytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability.

The CGIHTTPServer module in Python 2.7.5 and 3.3.4 does not properly handle URLs in which URL encoding is used for path separators, which allows remote attackers to read script source code or conduct directory traversal attacks and execute unintended code via a crafted character sequence, as demonstrated by a %2f separator.

Affected Node.js versions can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system.
