Linux Distros Unpatched Vulnerability : CVE-2026-119196
high Nessus Plugin ID 374106
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.5, constructed BIT STRING decoding repeatedly shifts and copies the complete bit value accumulated from earlier fragments. Attacker-controlled BER or CER input contains many constructed BIT STRING fragments; schema-driven DER also accepts a definite-length constructed BIT STRING. BitStringPayloadDecoder repeatedly calls BitString.fromOctetString with the prior bitString as prepend, shifting an ever-growing SizedInteger for each fragment and causing quadratic work.
Large fragmented values can exhaust CPU during decode() without requiring later conversion or formatting.
This issue is fixed in version 0.6.5. (CVE-2026-119196)
Note that Nessus relies on the presence of the package as reported by the vendor.
