[ASA-202012-24] openssl: denial of service
Arch Linux Security Advisory ASA-202012-24 ========================================== Severity: High Date : 2020-12-16 CVE-ID : CVE-2020-1971 Package : openssl Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-1335 Summary ======= The package openssl before version 1.1.1.i-1 is vulnerable to denial of service. Resolution ========== Upgrade to 1.1.1.i-1. # pacman -Syu "openssl>=1.1.1.i-1" The problem has been fixed upstream in version 1.1.1.i. Workaround ========== None. Description =========== A denial of service security issue was discovered in OpenSSL before 1.1.1i. The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. Impact ====== A remote attacker might be able to cause a crash by tricking a vulnerable client or server into checking a malicious certificate against a malicious CRL.
