CVE-2026-54900

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, when in usual mode with createid enabled, Oj::Parserparse is vulnerable to heap corruption via a negative-size memcpy. When a JSON object key is exactly 65,535 bytes long, an integer...

CVE-2026-49432

CVE-2026-49432 affects Apache ActiveMQ, including ActiveMQ All and ActiveMQ Stomp, due to improper input validation on STOMP exposure. A remote unauthenticated attacker can trigger denial-of-service by sending a negative content-length to an exposed STOMP connector. On the NIO STOMP transport, an...

CVE-2026-57235

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, Nokogiri::XML::NodeSet and its alias slice checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then...

CVE-2026-57235

CVE-2026-57235 affects Nokogiri (Ruby) prior to 1.19.4. The bug is in Nokogiri::XML::NodeSet#[] (and #slice) where the index check used a 32‑bit truncated copy, allowing a large negative index to pass bounds checks and be used with full width. Result: on CRuby an out‑of‑bounds read that typically...

libsolv: Heap buffer overflow in libsolv repo_add_solv via negative maxsize from crafted .solv file

A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted .solv file containing negative size values in the repoaddsolv function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could...
