CVE-2026-67192
Description détaillée
Xlight FTP Server before 3.9.5 contains a pre-authentication stack buffer overflow vulnerability that allows unauthenticated attackers to corrupt stack memory by sending malformed SSH packets when a GCM cipher is negotiated. Attackers can craft packets with an unvalidated length field passed directly to the GCM decrypt function, overwriting the stack cookie and return address to potentially achieve remote code execution before any authentication occurs.

CVE-2026-8339
A SQL injection vulnerability exists in the Coverity Connect SOAP API for versions between 2024.6.0 and 2026.3.0 (inclusive). A malicious, authenticated threat actor who sends a specially crafted payload can achieve full read access to database contents and other unauthorized commands.
CVE-2026-8338
A Spring Security authentication and authorization bypass exists in Coverity Connect versions between 2023.6.0 and 2026.3.0. An unauthenticated malicious threat actor that can send a specially crafted HTTP request is able to bypass authentication and authorization controls on certain API endpoints to access data within Coverity.
CVE-2026-67194
Courier IMAP before 6.0.1 and Courier Mail Server before 2.0.2 allow authenticated IMAP users to crash the imapd process via deeply nested parenthesized SEARCH queries. The SEARCH command parser (alloc_search_key in searchinfo.C) recursively descends on nested parenthesized groups through a mutual recursion chain with alloc_search_andlist() and alloc_search_notkey(), with no depth limit. Courier IMAP has no overall command line length limit, making exploitation trivial. A single IMAP command with ~2500 nested parentheses overflows the 8MB default stack, causing SIGSEGV.
