CVE-2026-49494

Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value taken from the IPv6 fixed header's payload length field by the size of each IPv6 extension header without validating it, so...

USN-8401-1: Netty vulnerabilities

It was discovered that Netty's HTTP proxy handler did not properly validate headers when constructing CONNECT requests. An attacker could possibly use this issue to inject arbitrary HTTP headers into CONNECT requests. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS,...

serialize-javascript: serialize-javascript: Denial of Service via specially crafted array-like object serialization

A flaw was found in serialize-javascript. An attacker can exploit this vulnerability by providing a specially crafted "array-like" object with an excessively large length property during the serialization process. This action causes the application to enter an intensive loop, leading to 100% CPU...
