Astra Linux – Vulnerability in musl

A security flaw has been discovered in musl libc up to version 1.2.6. The affected component is the iconv function in the src/locale/iconv.c file of the GB18030 4-byte Decoder component. Performing certain manipulations results in inefficient algorithmic complexity. The attack must be initiated...

CVE-2026-49250: Inefficient Algorithmic Complexity

Conform, a type-safe form validation library, allows the parsing of nested objects in the form of object.property. From 1.8.0 until 1.19.4, the parseSubmission future API in packages/conform-dom/formdata.ts repeatedly scans FormData or URLSearchParams entries by each unique field name. An...

CVE-2026-12882: Inefficient Algorithmic Complexity

icalendar has Algorithmic Complexity in Equality

SummaryComponent.eq compares subcomponents in O2^n time relative to nesting depth. Because the parser accepts arbitrarily nested components, a sub-kilobyte .ics file is enough to make a single equality check run for minutes or hang indefinitely. Any application that compares parsed components ==,...

The push to stop algorithms controlling social media feeds has begun

Remember when social media was filled only with posts from your friends, rather than what an algorithm decided you wanted to see? So does the Australian government, and it wants that internet back. Yesterday, the government released draft legislation outlining a Digital Duty of Care. The proposal...

CVE-2026-87822: Inefficient Algorithmic Complexity

t-digest versions 3.1 through 3.3 fail to validate centroid means during deserialization in MergingDigest.fromBytes, allowing attackers to inject NaN values that bypass validation checks. Attackers can craft malicious serialized digests containing NaN centroids that degrade sorting performance fr...

The vulnerability of the JSON processing library and stream-json, related to algorithmic complexity, allows attackers to cause service failures.

The vulnerability of the JSON processing library and stream-json is related to algorithmic complexity. Exploiting this vulnerability could allow an attacker to cause a service failure...
