All news with #buffer overflow tag

⚠️ Rockwell Automation reports a stack-based buffer overflow in its Lifecycle Services with Cisco offerings related to the Cisco IOS XE SNMP subsystem (CVE-2025-20352). An authenticated remote actor with low privileges can trigger a denial-of-service, and an actor with higher privileges and administrative access may achieve arbitrary code execution as root. A CVSS v4 score of 6.3 and a CVSS v3 score of 7.7 are provided. Rockwell and Cisco publish updates and mitigations; CISA advises minimizing network exposure and applying vendor fixes or recommended workarounds.

⚠️ Rockwell Automation has published an advisory for Stratix switches informing operators of a stack-based buffer overflow in the SNMP subsystem derived from Cisco IOS XE (CVE-2025-20352). A remote, authenticated attacker with knowledge of SNMPv2c read-only community strings or valid SNMPv3 credentials could cause a denial-of-service, while administrative (privilege 15) credentials may permit arbitrary code execution as root. Affected models include Stratix 5700, 5400, 5410, 5200, and 5800; Rockwell and CISA recommend applying Cisco workarounds, implementing network isolation, using secure remote access, and following Rockwell advisory SD1749.

🛡️ Cisco released security updates addressing a high-severity zero-day, tracked as CVE-2025-20352, in IOS and IOS XE. The flaw is a stack-based buffer overflow in the SNMP subsystem that allows authenticated remote attackers with low privileges to trigger DoS, and high-privileged actors to execute code as root on affected devices. Cisco reports exploitation in the wild after Administrator credentials were compromised and urges customers to upgrade; as a temporary mitigation it recommends limiting SNMP access to trusted users.

🔐 Siemens has disclosed multiple vulnerabilities in the integrated User Management Component (UMC) that could allow unauthenticated remote attackers to execute arbitrary code or cause denial-of-service. A stack-based buffer overflow (CVE-2025-40795) and several out-of-bounds read issues (CVE-2025-40796–40798) are reported, with CVSS v4 scores up to 9.3. Siemens recommends updating UMC to V2.15.1.3 or later and, where feasible, blocking TCP ports 4002 and 4004; Siemens notes no fixes are planned for SIMATIC PCS neo V4.1 and V5.0.

🔒 Apple introduced Memory Integrity Enforcement (MIE) on the new iPhone 17 and iPhone Air, implemented in the A19 and A19 Pro chips to deliver always-on memory safety across the kernel and more than 70 userland processes. MIE combines secure memory allocators, an enhanced synchronous Memory Tagging system called EMTE, and Tag Confidentiality Enforcement (TCE) to detect and block buffer overflows and use-after-free bugs. Apple says the design preserves performance while hardening devices against targeted mercenary spyware and exploitation of memory-corruption vulnerabilities.

🛡️ ABB has disclosed critical vulnerabilities in its ASPECT, NEXUS, and MATRIX building management and automation products that permit authentication bypass, unauthenticated critical functions, and a classic buffer overflow. Assigned CVEs include CVE-2025-53187, CVE-2025-7677, and CVE-2025-7679 with CVSS v4 scores up to 9.3. ABB resolved CVE-2025-53187 in firmware 3.08.04-s01 and recommends updating affected devices, avoiding direct Internet exposure, restricting network access segments, requiring VPN-based remote access, and changing default credentials to reduce risk.

⚠️ Delta Electronics has identified two critical vulnerabilities in COMMGR (v2.9.0 and earlier) — a stack-based buffer overflow (CVE-2025-53418) and a code injection flaw (CVE-2025-53419) — that can enable arbitrary code execution via crafted .isp files. Delta and CISA rate the combined risk as high (CISA lists CVSS v4 8.8) and recommend upgrading to v2.10.0 or later. Additional mitigations include network segmentation, limiting Internet exposure, and using secure remote access methods. CISA reports no known public exploitation at this time.
