js-yaml: js-yaml: Denial of Service via crafted YAML documents

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker could exploit this vulnerability by providing a specially crafted YAML document containing a chain of mappings with merge keys. This could cause the parser to consume excessive CPU resources, leading to a Denial o...

tar: node-tar: Denial of Service via crafted gzip bomb

A flaw was found in node-tar, a tar archive manipulation library for Node.js. This vulnerability allows a remote attacker to craft a small gzip bomb, which, when processed, can lead to the exhaustion of disk space and CPU resources. This occurs because node-tar does not enforce strict limits on t...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.1 contains a security vulnerability. This vulnerability stems from the ceph filesystem’s cephcapreclaimwork function, which repeatedly requeues itself when cephtrimdentries returns -EAGAIN, creating a busy loop and leading to exhaustion of CPU resources...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the s390/percpu MVIYPERCPU macro. When old versions of binutils are used, the whitespace between quoted parameters is discarded, leading to an error in the assembly macro parameter parsing. As a result, the mviy...

CVE-2026-39820: rebuild against golang = 1.22.9-1.el92.tuxcare.els13 to fix quadratic complexity in consumeComment in net/mail, preventing CPU exhaustion and excessive memory allocation from well-crafted input to ParseAddress, ParseAddressList and ParseDate...

FFmpeg: Denial of Service via crafted RTP/ASF stream

A flaw was found in FFmpeg. A remote attacker can exploit an infinite loop vulnerability in the RTP/ASF demuxer by sending a specially crafted stream. This vulnerability occurs because the rtpasffixheader function does not properly validate the size of data chunks, preventing the processing loop...

PYSEC-2026-3847 HTTPX2: Quadratic SSE line buffering can cause CPU denial of service

Summary HTTPX2's Server-Sent Events SSE parser repeatedly copied and rescanned buffered text when a server split one unterminated line across many response chunks. The total work grows quadratically with the length of the line. An attacker-controlled or compromised SSE endpoint can exploit this...

vLLM: Derender endpoints decode caller-supplied GenerateResponse token IDs without output bounds

SummaryThe /v1/completions/derender and /v1/chat/completions/derender endpoints accept caller-supplied GenerateResponse objects and postprocess every nested choices.tokenids list directly. Unlike the normal render/generate path, derender does not enforce model context length, resolved maxtokens,...

NLTK: Uncontrolled resource consumption in RecursiveDescentParser via ambiguous or left-recursive grammars

nltk.parse.RecursiveDescentParser and SteppingRecursiveDescentParser enumerate parses top-down with no bound on the number of recursive steps. A small, crafted context-free grammar makes a short input consume unbounded CPU and/or exhaust the Python recursion stack, pinning a process indefinitely ...

NLTK: Quadratic CPU Exhaustion in `XMLCorpusView._read_xml_fragment()`

SummaryXMLCorpusView.readxmlfragment reads a corpus file in 1 KiB blocks, appendingeach block to a growing fragment string, then calls VALIDXMLRE.matchfragmenton the full accumulated buffer every iteration. Because each iteration rescans theentire accumulated fragment, the total amount of work...

Because each iteration rescans the entire accumulated fragment, the total amount of wor...

PYSEC-2026-3923 sqlparse: Reindentation of tuple lists causes near-cap quadratic CPU consumption

Summary When SQL is formatted with reindentation enabled, ReindentFilter repeatedly rebuilds prefixes of the current statement to calculate token offsets. An attacker who controls SQL sent to this opt-in formatting path can supply a parenthesized tuple list that remains just below the...

eml_parser vulnerable to DoS via deeply nested parens in Received headers

Summaryemlparser strips parenthesised CFWS comments from Received: headers using a regex-based fix-point loop. The loop has quadratic time complexity in the number of nested parens. A single Received: header containing 5,000 nested parens causes 1.3 seconds of CPU saturation per parsed message;...
