Packet Storm

Ubuntu Security Notice 5730-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Ubuntu Security Notice 5731-1 - It was discovered that multipath-tools incorrectly handled symlinks. A local attacker could possibly use this issue, in combination with other issues, to escalate privileges. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 22.10. It was discovered that multipath-tools incorrectly handled access controls. A local attacker could possibly use this issue, in combination with other issues, to escalate privileges.

PatrIoT provides a four-stage IoT vulnerability research methodology built on top of four key elements: logical attack surface decomposition, compilation of top 100 weaknesses, lightweight risk scoring, and step-by-step penetration testing guidelines. The proposed methodology is evaluated with multiple IoT products. The results indicate that PatrIoT allows cyber security practitioners without much experience to advance vulnerability research activities quickly and reduces the risk of critical IoT penetration testing steps being overlooked.

In the function AppleAVDUserClient::decodeFrameFig, a location in the decoder's IOSurface input buffer is calculated, and then bzero is called on it. The size of this IOSurface's allocation is controllable by the userspace caller, so the calculated pointer can go out of bounds, leading to memory corruption. This issue could potentially allow an unprivileged local application to escalate its privileges to the kernel.

In AppleAVD.kext, pixel buffers are mapped by calling AppleAVDUserClient::_mapPixelBuffer, which eventually calls AppleAVD::allocateKernelMemoryInternal. If the buffer is an IOSurface, the function calls IOSurface::deviceLockSurface before allocating memory by calling prepare. But when a pixel buffer is unmapped by calling AppleAVDUserClient::_unmapPixelBuffer, which calls AppleAVD::deallocateKernelMemoryInternal, the IOSurface is not locked before calling complete. This means that mapping and unmapping can occur at the same time, leading to kernel memory corruption. This bug could allow escalation to kernel privileges from a local app.

This Metasploit module exploits the Git fetch command in the Gitea repository migration process to allow for remote command execution on the system. This vulnerability affect Gitea versions prior to 1.16.7.

Botan is a C++ library of cryptographic algorithms, including AES, DES, SHA-1, RSA, DSA, Diffie-Hellman, and many others. It also supports X.509 certificates and CRLs, and PKCS #10 certificate requests, and has a high level filter/pipe message processing system. The library is easily portable to most systems and compilers, and includes a substantial tutorial and API reference. This is the current stable release.

Debian Linux Security Advisory 5283-1 - Several flaws were discovered in jackson-databind, a fast and powerful JSON library for Java.

Debian Linux Security Advisory 5279-2 - Several vulnerabilities were discovered in Wordpress, a web blogging tool. They allowed remote attackers to perform SQL injection, create open redirects, bypass authorization access, or perform Cross-Site Request Forgery (CSRF) or Cross-Site Scripting (XSS) attacks. The wordpress package released in DSA-5279-1 had incorrect dependencies that could not be satisfied in Debian stable. This update corrects the problem.

Ubuntu Security Notice 5729-1 - It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service. Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel contained an out-of-bounds read vulnerability in the x86 JIT compiler. A local attacker could possibly use this to cause a denial of service or expose sensitive information.
