CVE-2026-59980

The python-hyper/hpack library, often used as a dependency for the python-hyper/h2 HTTP/2 implementation, is vulnerable to run-away computation due to unbounded variable integer decoding . Malformed input can trigger an O(n^2) runtime, potentially blocking further processing. A fix is available i...

CVE-2026-59980

hpack is an HTTP/2 Header Encoding for Python. Prior to version 4.2.0, unbounded variable integer decoding can cause run-away computation on malformed input leading to On^2 runtime, effectively blocking further processing with large enough unsanitized input. A fix is available in python-hyper/hpa...

CVE-2026-58226

CVE-2026-58226 affects the hpax component of elixir-mint. The vulnerability is in Elixir.HPAX.Types:decode_remaining_integer/3 , which decodes HPACK integers without an upper bound, allowing an unauthenticated attacker to trigger excessive CPU and transient memory via a small HTTP/2 header block....

EEF-CVE-2026-58226 Unauthenticated denial-of-service via unbounded HPACK integer decoding in hpax

Summary Inefficient Algorithmic Complexity vulnerability in elixir-mint hpax allows unauthenticated denial-of-service via unbounded HPACK integer decoding. hpax decodes HPACK variable-length integers with no upper bound on the decoded value or the number of continuation octets...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the INTEGERdecodeoer function. An attacker can cause a denial of service or trigger incorrect integer interpretation in downstream applications by submitting a maliciously crafted, zero-length OER payload for a...

CVE-2026-45615

ASN.1 compiler mouse07410/asn1c (1.4 and earlier) contains a memory-safety flaw in the OER decoding skeleton (INTEGER_oer.c). Parsing a crafted, zero-length OER payload for a variable-length, non-negative INTEGER can skip required-byte validation before extracting the MSB, causing a precise 1-byt...

CVE-2026-45615 mouse07410/asn1c: 1-byte Heap Out-of-Bounds Read in `INTEGER_decode_oer` via Malformed OER Payload

mouse07410/asn1c is an ASN.1 compiler. In 1.4 and earlier, a memory safety vulnerability was identified in the OER decoding skeleton files generated by asn1c specifically INTEGERoer.c. When parsing a maliciously crafted, zero-length OER payload for a variable-length, non-negative INTEGER type, th...
