SYNOLOGY VPN PLUS ENCRYPT ALL DATA CODE

This might result in a crash (causing a Denial of Service attack). If a malicious actor can cause an application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL functions then this issue could be hit. Access to private memory contents (private keys or sensitive data) can also be acquired.During these attacks, hackers can make impacted apps stop functioning.These strings are in danger of being exploited by malicious actors who want to perform DoS attacks.This happens when ASN.1 strings are processed.This can lead to a buffer overflow when EVP_PKEY_decrypt() is called by the application a second time with a buffer that is too small.

The danger that comes out of this vulnerability is the possibility of remote code execution attacks or application crashing.Ī bug in the implementation of the SM2 decryption code means that the calculation of the buffer size required to hold the plaintext returned by the first call to EVP_PKEY_decrypt() can be smaller than the actual size required by the second call.

This can be found in the SM2 cryptographic algorithm.The cause of this first vulnerability is represented by a heap-based buffer overflow.

As per their report, the bugs have the following characteristics: Synology published yesterday a security advisory detailing these flaws. The identified OpenSSL vulnerabilities could lead to remote code execution (RCE) and DoS attacks (denial-of-service). OpenSSL Vulnerabilities: Detailing the Flaws The Synology enterprise has made public the fact that various products of the company are impacted at the present moment by the recently discovered OpenSSL vulnerabilities.
