Dovecot IMAP server versions 2.2 and 2.3 suffer from denial of service and resource exhaustion vulnerabilities.

Dovecot IMAP server versions 2.2 and 2.3 have an issue where a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive. With 100k header lines CPU usage is already 12 seconds, and in a production environment we observed 500k header lines taking 18 minutes to parse. Since this can be triggered by external actors sending emails to a victim, this is a security issue.

The following presentation at this year's DEF CON was brought to our attention on the SQLx Discord: > SQL Injection isn't Dead: Smuggling Queries at the Protocol Level > <http://web.archive.org/web/20240812130923/https://media.defcon.org/DEF%20CON%2032/DEF%20CON%2032%20presentations/DEF%20CON%2032%20-%20Paul%20Gerste%20-%20SQL%20Injection%20Isn't%20Dead%20Smuggling%20Queries%20at%20the%20Protocol%20Level.pdf> > (Archive link for posterity.) Essentially, encoding a value larger than 4GiB can cause the length prefix in the protocol to overflow, causing the server to interpret the rest of the string as binary protocol commands or other data. It appears SQLx _does_ perform truncating casts in a way that could be problematic, for example: <https://github.com/launchbadge/sqlx/blob/6f2905695b9606b5f51b40ce10af63ac9e696bb8/sqlx-postgres/src/arguments.rs#L163> This code has existed essentially since the beginning, so it is reasonable to assume that all published versions `<= 0.8.0` a...

A stalkerware researcher has found that Trackimo and its Tracki GPS tracker have some underlying major security flaws exposing location data.

A new type of malware called UULoader is being used by threat actors to deliver next-stage payloads like Gh0st RAT and Mimikatz. The Cyberint Research Team, which discovered the malware, said it's distributed in the form of malicious installers for legitimate applications targeting Korean and Chinese speakers. There is evidence pointing to UULoader being the work of a Chinese speaker due to the

Cybersecurity researchers have uncovered a surge in malware infections stemming from malvertising campaigns distributing a loader called FakeBat. "These attacks are opportunistic in nature, targeting users seeking popular business software," the Mandiant Managed Defense team said in a technical report. "The infection utilizes a trojanized MSIX installer, which executes a PowerShell script to

Millennials, equipped with a strong sense of privacy in relationships, are still sharing their online accounts at similar rates of Gen Z.

Malicious actors are using a cloud attack tool named Xeon Sender to conduct SMS phishing and spam campaigns on a large scale by abusing legitimate services. "Attackers can use Xeon to send messages through multiple software-as-a-service (SaaS) providers using valid credentials for the service providers," SentinelOne security researcher Alex Delamotte said in a report shared with The Hacker News.

An adversary could exploit these vulnerabilities by injecting malicious libraries into Microsoft's applications to gain their entitlements and user-granted permissions.

A newly patched security flaw in Microsoft Windows was exploited as a zero-day by Lazarus Group, a prolific state-sponsored actor affiliated with North Korea. The security vulnerability, tracked as CVE-2024-38193 (CVSS score: 7.8), has been described as a privilege escalation bug in the Windows Ancillary Function Driver (AFD.sys) for WinSock. "An attacker who successfully exploited this
