MGASA-2020-0325 Updated golang packages fix security vulnerability

Servers where the Handler concurrently reads the request body and writes a response can encounter a data race and crash. The httputil.ReverseProxy Handler is affected CVE-2020-15586. Certain invalid inputs to ReadUvarint or ReadVarint could cause those functions to read an unlimited number of byt...

The vulnerability of the s390/s390x memory controller component in Linux operating systems allows attackers to disclose sensitive information that should be protected.

The vulnerability of the s390/s390x memory controller component in Linux operating systems is related to incorrect handling of zero bytes or Nul characters during data exchange. Exploiting this vulnerability can allow an attacker to disclose sensitive information that is protected by security...

go -- encoding/binary: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs

The Go project reports: Certain invalid inputs to ReadUvarint or ReadVarint could cause those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This could lead to processing more input than expected when the caller is reading directly from the...

GHSA-VH7M-P724-62C2 Signature Malleabillity in elliptic

The Elliptic package before version 6.5.3 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature...

Buffer overflow

RIOT 2020.04 has a buffer overflow in the base64 decoder. The decoding function base64decode uses an output buffer estimation function to compute the required buffer capacity and validate against the provided buffer size. The base64estimatedecodesize function calculates the expected decoded size...

DEBIAN-CVE-2020-4067

In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client an attacker could use their connection to intelligently query coturn to get interesting bytes in the...

CVE-2020-4067 Improper Initialization in coturn

In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client an attacker could use their connection to intelligently query coturn to get interesting bytes in the...

The vulnerability of the ssl3_read_bytes function (record/rec_layer_s3.c) in the OpenSSL library, which allows a hacker to cause a service failure.

The vulnerability of the ssl3readbytes function in the record/reclayers3.c file of the OpenSSL library exists due to insufficient validation of input data. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

Insecure RSA Signature Validation

jsrsasign does not properly validate RSA signatures. The decryption implementation does not detect ciphertext modification prepended by \0 bytes to ciphertexts, allowing an attacker to prepend NULL bytes with the goal of triggering memory corruption issues...
