### Summary When executing the following simple query, the `vtgate` will go into an endless loop that also keeps consuming memory and eventually will OOM. ### Details When running the following query, the `evalengine` will try evaluate it and runs forever. ``` select _utf16 0xFF ``` The source of the bug lies in the collation logic that we have. The bug applies to all `utf16`, `utf32` and `ucs2` encodings. In general, the bug is there for any encoding where the minimal byte length for a single character is more than 1 byte. The decoding functions for these collations all implement logic like the following to enforce the minimal character length: https://github.com/vitessio/vitess/blob/8f6cfaaa643a08dc111395a75a2d250ee746cfa8/go/mysql/collations/charset/unicode/utf16.go#L69-L71 The problem is that all the callers of `DecodeRune` expect progress by returning the number of bytes consumed. This means that if there's only 1 byte left in an input, it will here return still `0` and ...

The Trix editor, versions prior to 2.1.1, is vulnerable to arbitrary code execution when copying and pasting content from the web or other documents with markup into the editor. The vulnerability stems from improper sanitization of pasted content, allowing an attacker to embed malicious scripts which are executed within the context of the application. **Vulnerable Versions**: Up to 2.1.0 **Fixed Version**: 2.1.1 **Vector**: - **Bug 1**: When copying content manipulated by a script, such as: ```js document.addEventListener('copy', function(e){ e.clipboardData.setData('text/html', '<div><noscript><div class="123</noscript>456<img src=1 onerror=alert(1)//"></div></noscript></div>'); e.preventDefault(); }); ``` and pasting into the Trix editor, the script within the content is executed. - **Bug 2**: Similar execution occurs with content structured as: ```js document.write(`copy<div data-trix-attachment="{"contentType":"text/html","content":"&l...
### Summary If PDF.js is used to load a malicious PDF, and PDF.js is configured with `isEvalSupported` set to `true` (which is the default value), unrestricted attacker-controlled JavaScript will be executed in the context of the hosting domain. ### Patches [This patch](https://github.com/wojtekmaj/react-pdf/commit/671e6eaa2e373e404040c13cc6b668fe39839cad) forces `isEvalSupported` to `false`, removing the attack vector. ### Workarounds Set `options.isEvalSupported` to `false`, where `options` is `Document` component prop. ### References - [GHSA-wgrm-67xf-hhpq](https://github.com/mozilla/pdf.js/security/advisories/GHSA-wgrm-67xf-hhpq) - https://github.com/mozilla/pdf.js/pull/18015 - https://github.com/mozilla/pdf.js/commit/85e64b5c16c9aaef738f421733c12911a441cec6 - https://bugzilla.mozilla.org/show_bug.cgi?id=1893645
