inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic
Last updated 11 July 2025
An old inffast.c optimization turns out to not be optimal anymore with modern compilers, and furthermore was not compliant with the C standard, for which decrementing a pointer before its allocated memory is undefined.

The sshagentchanneldata function in PuTTY before 0.68 allows remote attackers to have unspecified impact via a large length value in an agent protocol message and leveraging the ability to connect to the Unix-domain socket representing the forwarded agent connection, which trigger a buffer overflow.
Cross-site scripting (XSS) vulnerability in the navpath function in lib/viewvc.py in ViewVC before 1.0.14 and 1.1.x before 1.1.26 allows remote attackers to inject arbitrary web script or HTML via the navdata name.
The AliasHandler component in PostfixAdmin before 3.0.2 allows remote authenticated domain admins to delete protected aliases via the delete parameter to delete.php, involving a missing permission check.
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.
A vulnerability was found in gnutls. There was an insufficient error checking in the stream reading functions. While parsing a maliciously crafted OpenPGP certificate an out of memory error could occur.

A new exploitation technique called key reinstallation attacks used to break Wi-Fi handshakes that negotiate session keys was discovered. These attacks target the Wi-Fi/WPA2 standard. An adversary can trick a client or Access Point (AP) into reinstalling an already-in use pairwise key in 4-way handshake. While reinstalling the already in-use key, the associated packet number (sometimes also called nonce) and receive replay counter is reset. This causes nonce reuse, voiding any security the underlying encryption protocol is supposed to provide. For example, it allows decryption or injection of frames, and enables an attacker to replay frames.
Added checks to prevent overflow in rle file.
