CVE-2026-23490

A flaw was found in pyasn1, a generic ASN.1 library for Python. A remote attacker could exploit this vulnerability by sending a specially crafted RELATIVE-OID with excessive continuation octets. This input validation vulnerability leads to memory exhaustion, resulting in a Denial of Service (DoS) for the affected system.

Threats
Impact Important
CVE-2026-30922

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE (0x30) or SET (0x31) tags with Indefinite Length (0x80) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a RecursionError or consumes all available memory (OOM), crashing the host application.

7.5 (High)
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Known not affected 5 products, the same list as for CVE-2026-23490

Impact Important
CVE-2026-40192

A flaw was found in Pillow, a Python imaging library. This vulnerability allows a remote attacker to trigger a denial of service (DoS) by providing a specially crafted FITS image file. The library's failure to limit the amount of GZIP-compressed data during decoding can lead to unbounded memory consumption, causing the system to crash or experience severe performance issues.

7.5 (High)
