Threats tagged 'brew-smbclient-ng-cve-2026-119194'

CVE-2026-119194 is a high-severity vulnerability in pyasn1 used by smbclient-ng (>=3.1.0) where schemaless decoding of BER, CER, or DER data with many distinct long tag IDs causes quadratic CPU usage. This can lead to CPU exhaustion and reduced service availability when processing attacker-controlled inputs. The vulnerability arises from inefficient handling of tag sets during decoding, causing excessive CPU consumption without affecting confidentiality or integrity.
