Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: CVE-2026-59886)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an unauthenticated remote attacker to cause denial of service by exhausting CPU and memory in applications using pyasn1.

The vulnerability exists due to exact big-integer exponentiation during float conversion of ASN.1 REAL values with large exponents, triggered by operations on decoded objects rather than decoding alone. An unauthenticated remote attacker can supply a compact encoded REAL value that hangs the process when the application prints or compares it.
