Date : 2020-04-22
CVE-ID : CVE-2020-1967
Package : lib32-openssl
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1142
The package lib32-openssl before version 1.1.1.g-1 is vulnerable to
denial of service.
Upgrade to 1.1.1.g-1.
The problem has been fixed upstream in version 1.1.1.g.
None.
A NULL pointer dereference has been found in OpenSSL versions 1.1.1d,
1.1.1e and 1.1.1f. Server or client applications that call the
SSL_check_chain() function during or after a TLS 1.3 handshake may
crash due to a NULL pointer dereference as a result of incorrect
handling of the “signature_algorithms_cert” TLS extension. The crash
occurs if an invalid or unrecognised signature algorithm is received
from the peer. This could be exploited by a malicious peer in a Denial
of Service attack.
A malicious server or client may crash an openssl/libssl process by
providing a maliciously-crafted SSL handshake
