pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

Impact The BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadratically in input size...

CVE-2026-59884

A flaw was found in pyasn1, a generic ASN.1 library for Python. The Basic Encoding Rules BER decoder, used by CER and DER codecs, processes long-form tags by accumulating continuation octets without an upper bound. A remote attacker can exploit this by providing a specially crafted input, leading...

MKP: Unbounded Pod Log Read via Attacker-Controlled `limitBytes`/`tailLines` Causes Memory Exhaustion

Unbounded Pod Log Read via Attacker-Controlled limitBytes/tailLines Causes Memory Exhaustion Summary The MKP Model Context Protocol for Kubernetes server exposes a getresource MCP tool that proxies Kubernetes pod log requests. User-supplied limitBytes and tailLines parameters are parsed as...

CVE-2026-59884 pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with C...

EUVD-2026-42534

A denial-of-service vulnerability caused by unbounded resource allocation was discovered in the audit logging functionality, due to a missing size limit on input recorded into audit entries. An unauthenticated attacker can submit requests containing excessively large input that is recorded into...

CVE-2026-31984 DoS through oversized audit log entries in Guardian/CMC before 26.2.0

A denial-of-service vulnerability caused by unbounded resource allocation was discovered in the audit logging functionality, due to a missing size limit on input recorded into audit entries. An unauthenticated attacker can submit requests containing excessively large input that is recorded into...

CVE-2026-59873 node-tar: Decompression/parse DoS via unlimited input

node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small crafted gzip bomb to exhaust disk spac...
