SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. There is no fixed version for Debian:9 openssl. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. This script is distributed by some operating systems in a manner where it is automatically executed. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. Upgrade Debian:9 openssl to version 1.1.0l-1~deb9u6 or higher. The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. See How to fix? for Debian:9 relevant fixed versions and status. Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by Debian:9. Upgrade Debian:9 libx11 to version 2:1.6.4-3+deb9u4 or higher. ![]() For example, if the victim encounters malicious terminal control sequences for color codes, then the attacker may be able to take full control of the running graphical session. The user-controlled data exceeding the maximum size is then interpreted by the server as additional X protocol requests and executed, e.g., to disable X server authorization completely. The libX11 XLookupColor request (intended for server-side color lookup) contains a flaw allowing a client to send color-name requests with a name longer than the maximum size allowed by the protocol (and also longer than the maximum packet size for normal-sized packets). LookupCol.c in X.Org X through X11R7.7 and libX11 before 1.7.1 might allow remote attackers to execute arbitrary code. Note: Versions mentioned in the description apply only to the upstream libx11 package and not the libx11 package as distributed by Debian:9. ![]()
