Information Disclosure

Description

A security flaw has been discovered in musl libc up to 1.2.6. Affected is the function iconv of the file src/locale/iconv.c of the component GB18030 4-byte Decoder. Performing a manipulation results in inefficient algorithmic complexity. The attack must be initiated from a local position. To fix this issue, it is recommended to deploy a patch.

Analysis

Inefficient algorithmic complexity in musl libc's GB18030 4-byte decoder (iconv function in src/locale/iconv.c) affects versions up to 1.2.6 and allows local authenticated attackers to cause availability impact through resource exhaustion. The vulnerability requires local access and authenticated privileges but enables denial of service via algorithmic complexity exploitation. …
