Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-24903)
The vulnerability allows a remote attacker to perform a denial of service or potentially execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing data in imtcp, imptcp, imgssapi, and imhttp modules used for TCP syslog reception. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service or potentially execute arbitrary code on the target system.
Successful exploitation of this vulnerability is possible if the attacker is able to directly send specially crafted messages to the rsyslog daemon or by injecting specially crafted data into log files. Vulnerability exploitation in the second scenario requires that the rsyslog client supports octet-counted framing, which is not a default configuration.
2) Input validation error (CVE-ID: CVE-2022-43908)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Buffer overflow (CVE-ID: CVE-2020-12321)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to a boundary error. A remote attacker on the local network can trigger memory corruption and execute arbitrary code on the target system with elevated privileges.
4) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
5) Input validation error (CVE-ID: CVE-2022-1271)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation when processing filenames with two or more newlines. A remote attacker can force zgrep or xzgrep to write arbitrary files on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-439210)
The vulnerability allows a local attacker to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions, which leads to security restrictions bypass and privilege escalation.
7) Stack-based buffer overflow (CVE-ID: CVE-2022-4378)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the __do_proc_dointvec() function. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.
8) Heap-based buffer overflow (CVE-ID: CVE-2022-37434)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing a large gzip header within inflateGetHeader in inflate.c. A remote attacker can pass a specially crafted file to the affected application, trigger heap-based buffer overflow and execute arbitrary code on the target system.
