CVE-2026-54592

The CVE-2026-54592 vulnerability affects Oj (Optimized JSON), a Ruby gem JSON parser/marshaller. In versions prior to 3.17.3, Oj::Doc#each_child can overflow a fixed-size stack buffer when recursively traversing deeply nested JSON, causing a DoS. The issue arises from a two-step chain in ext/oj/f...

CVE-2026-54500 Oj: intern.c form_attr has an uninitialized stack read

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.3, Oj.load in :object mode reads uninitialized stack memory and, for long keys, reads out of bounds when parsing a JSON object whose key is 254 bytes or longer. The interned bytes can surfac...

UBUNTU-CVE-2026-57585

MessagePack is the serializer implementation for Python msgpack.org. Prior to 1.2.1, there is an Out-of-bounds read/crash on Unpacker reuse after a caught error, potentially leading to a DoS attack. If the Unpacker is used repeatedly after an error occurs, the process may crash with a SEGV. This...

UBUNTU-CVE-2026-57204

pypdf is a free and open-source pure-python PDF library. Prior to 6.13.3, a maliciously crafted PDF can cause DoS. An attacker who uses this vulnerability can craft a PDF which leads to large memory usage, as MAXDECLAREDSTREAMLENGTH is sometimes ignored. This requires parsing a content stream...

CVE-2026-54696 Ruby JSON: JSON generator heap buffer overflow when streaming to an IO

Ruby JSON is a JSON implementation for Ruby. Versions 2.9.0 through 2.19.8 are vulnerable to heap buffer overflow when the JSON generator is provided with an oversized streamed object. When streaming to an IO JSON.dumpobj, io and JSON::Stategenerateobj, io can write past the internal JSON generat...

CVE-2026-53433

In fzf, CVE-2026-53433, the DoS arises from inefficient HTTP body processing in the --listen mode due to repeated string concatenation, giving quadratic time (O(n²)) for a crafted POST request with many small segments. This can cause a single malicious request to monopolize the single-threaded HT...

CVE-2026-53432

fzf is vulnerable to Integer Overflow leading to crash in FuzzyMatchV2 function. When input line length is approximately 2,200,000 bytes and pattern length is 999 bytes, the product overflows. The Go runtime detects the invalid slice bounds and terminates the process immediately with a...
