  "details": "## Summary\n\nThe DER parser used for application-supplied private keys did not safely validate encoded length values before converting them to `Int` values or allocating arrays.\n\nA malformed private-key file could encode a length that overflowed or wrapped around, or request an allocation much larger than the available input. This could cause parsing errors or an uncaught `OutOfMemoryError`, potentially terminating the application process.\n\n## Details\n\nThe issue was in `DerReader.readLength()` and primitive readers such as `readInteger()`.\n\n`readLength()` previously accepted up to 127 length octets and accumulated them into an `Int`:\n\n```kotlin\nlength = (length shl 8) or nextByte\n```\n\nThis permitted integer overflow. For example:\n\n- `0x1_0000_0001` wrapped to `1`.\n- `0x8000_0000` wrapped to `Int.MIN_VALUE`.\n\nPrimitive readers then allocated memory based on the resulting value without first checking it against the remaining input:\n\n```kotlin\nval bytes = ByteArray(length)\ndata.get(bytes)\n```\n\nA six-byte DER value declaring a 1 GiB INTEGER caused an immediate `OutOfMemoryError` when tested with a constrained JVM heap. Because `OutOfMemoryError` is not an `Exception`, it is not caught by the public-key authentication error handling and may terminate the application process.\n\nA zero-length DER INTEGER is also invalid, but it does not produce `BigInteger.ZERO`: Java throws `NumberFormatException` when constructing a `BigInteger` from an empty byte array. No weakened or usable cryptographic key has been demonstrated through this issue.\n\n## Attack Requirements\n\nThe affected DER parser processes private-key material explicitly supplied by the application through APIs such as:\n\n- `SshClient.authenticatePublicKey()`\n- `SshKeys.decodePemPrivateKey()`\n- `SshSigning.sign()`\n- `SshSigning.getPublicKey()`\n\nThe DER input is not populated from SSH server host keys or agent-forwarding requests. Exploitation therefore requires a user or application to load an attacker-provided private-key file. The issue is not remotely exploitable by an SSH server.\n\n## Impact\n\nSuccessful exploitation can cause:\n\n- Incorrect DER length interpretation due to integer wraparound\n- Excessive memory allocation\n- An uncaught `OutOfMemoryError`\n- Loss of availability of the affected application process\n\nThere is no demonstrated confidentiality or integrity impact.\n\n## Remediation\n\nThe DER parser now:\n\n- Rejects indefinite lengths\n- Explicitly limits long-form lengths to `Int.SIZE_BYTES` (four octets) and rejects values above `Int.MAX_VALUE`\n- Accumulates long-form lengths in a `Long` before converting to `Int`\n- Rejects truncated and non-minimal length encodings\n- Checks declared lengths against the remaining input before allocation or advancing the input position\n- Rejects zero-length DER INTEGER, BIT STRING, and OBJECT IDENTIFIER values where an empty encoding is invalid\n- Rejects non-canonical DER INTEGER encodings with redundant sign octets\n\nThe bounds checks are implemented in shared DER reader helpers and apply to INTEGER, OCTET STRING, BIT STRING, OBJECT IDENTIFIER, SEQUENCE, context-specific values, and skipped values. PKCS#1 RSA and SEC1 EC private keys pass application-supplied DER directly through these helpers. PKCS#8 input is parsed by the JCA provider, and OpenSSH private keys use a separate wire-format parser rather than `DerReader`.",

Header\n\n2. Data\n\nWhen a connection is made, the server is waiting for 4 bytes of data, which will be the header,\nand these 4 bytes would be parsed as uint32 size of the actual data to come.\n\nThen, in the function \u201chandleRequest\u201d this size is then used in order to allocate a payload on\nthe stack for the incoming data.\n\nAs this payload is allocated on the stack, this will allow overflowing the stack size allocated for\nthe relevant process with freely controlled data.\n\n* An attacker can crash the system. \n* An attacker can gain control over the system, specifically on the \u201cvtpm_server\u201d process\nwhich has very high privileges.",

This code path allows an unbounded read of the entire HTTP response message.\n\n### Impact\n\nIf an application using the OpAMP client is configured to use an OpAMP server that is attacker-controlled (or a network attacker can MitM the connection) and an extremely large body is returned in the response, the application could have its memory exhausted and create a denial-of-service condition.\n\n### Mitigation\n\nThe application\u0027s configured OpAMP server needs to behave maliciously. If the OpAMP server is a well-behaved implementation, response bodies should not be excessively large.\n\n### Workarounds\n\nNone known.\n\n### Remediation\n\n[#4116](https://github.com/open-telemetry/opentelemetry-dotnet-contrib/pull/4116) updates the OpAMP client HTTP transport to limit the maximum size of responses to 128KB.\n\n### Resources\n\n- [#2926](https://github.com/open-telemetry/opentelemetry-dotnet-contrib/pull/2926)\n- [#4116](https://github.com/open-telemetry/opentelemetry-dotnet-contrib/pull/4116)\n- [CWE-789](https://cwe.mitre.org/data/definitions/789.html)",
