An out-of-bounds write vulnerability exists in the PSD Header processing memory allocation functionality of Accusoft ImageGear 20.0. A specially-crafted malformed file can lead to memory corruption. An attacker can provide a malicious file to trigger this vulnerability.
Today, Talos is publishing a glimpse into the most prevalent threats we've observed between July 29 and Aug. 5. As with previous roundups, this post isn't meant to be an in-depth analysis. Instead, this post will summarize the threats we've observed by highlighting key behavioral characteristics, indicators of compromise, and discussing how our customers are automatically protected from these threats. As a reminder, the information provided for the following threats in this post is non-exhaustive and current as of the date of publication. Additionally, please keep in mind that IOC searching is only one part of threat hunting. Spotting a single IOC does not necessarily indicate maliciousness. Detection and coverage for the following threats is subject to updates, pending additional threat or vulnerability analysis. For the most current information, please refer to your Firepower Management Center, Snort.org, or ClamAV.net. For each threat described below, this blog post only lists 25...
For the right price, threat actors can get just about anything they want to launch a ransomware attack — even without technical skills or any previous experience.
Implicit Intent hijacking vulnerability in Smart View prior to SMR Aug-2022 Release 1 allows attacker to access connected device MAC address.
This Metasploit module creates a RAR file that can be emailed to a Zimbra server to exploit CVE-2022-30333. If successful, it plants a JSP-based backdoor in the public web directory, then executes that backdoor. The core vulnerability is a path-traversal issue in unRAR that can extract an arbitrary file to an arbitrary location on a Linux system. This issue is exploitable on Zimbra Collaboration versions 9.0.0 Patch 24 and below and 8.8.15 Patch 31 and below provided that UnRAR versions 6.11 or below are installed.

The July 17 attacks, according to Albania's National Agency of Information
This Tech Tip outlines how DevOps teams can address security integration issues in their CI/CD pipelines.
Ethermint is an Ethereum library. In Ethermint running versions before `v0.17.2`, the contract `selfdestruct` invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in the `DeleteAccount`function, all contracts that used the identical bytecode (i.e shared the same `CodeHash`) will also stop working once one contract invokes `selfdestruct`, even though the other contracts did not invoke the `selfdestruct` OPCODE. This vulnerability has been patched in Ethermint version v0.18.0. The patch has state machine-breaking changes for applications using Ethermint, so a coordinated upgrade procedure is required. A workaround is available. If a contract is subject to DoS due to this issue, the user can redeploy the same contract, i.e. with identical bytecode, so that the original contract's code is recovered. The new contract deployment restores the `bytecode hash -> bytecode` entry in the internal state.
A nascent service called Dark Utilities has already attracted 3,000 users for its ability to provide command-and-control (C2) services with the goal of commandeering compromised systems. "It is marketed as a means to enable remote access, command execution, distributed denial-of-service (DDoS) attacks and cryptocurrency mining operations on infected systems," Cisco Talos said in a report shared
