Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Double Free (CVE-ID: CVE-2023-25136)
The vulnerability allows a remote attacker to potentially execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the sshd(8) daemon. A remote non-authenticated attacker can send specially crafted data to the application, trigger a double free error and execute arbitrary code on the target system.
The vendor believes exploitation of this vulnerability has limitations as double free occurs "in the unprivileged pre-auth process that is subject to chroot(2) and is further sandboxed on most major platforms". Nevertheless we assign a high risk to this vulnerability.
2) Security features bypass (CVE-ID: CVE-2022-46908)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper implementation of the azProhibitedFunctions protection mechanism, which allows UDF functions such as WRITEFILE when relying on --safe for execution of an untrusted CLI script. A local user can escalate privileges on the system.
3) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.
4) Stack-based buffer overflow (CVE-ID: CVE-2022-3479)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the NSS_GetClientAuthData() function in /lib/ssl/authcert.c when accessing gnutls server without a user certificate in the database. A remote attacker can trigger a stack-based buffer overflow and crash the application using the affected library.
5) Input validation error (CVE-ID: CVE-2022-3171)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.
6) Integer overflow (CVE-ID: CVE-2022-42898)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to an integer overflow within the S4U2Proxy handler on 32-bit systems. A remote user can send specially crafted request to the KDC server, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Cleartext transmission of sensitive information (CVE-ID: CVE-2023-23914)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to state issues when handling multiple requests, which results in ignoring HSTS support. A remote attacker can perform MitM attack.8) Deserialization of Untrusted Data (CVE-ID: CVE-2022-1471)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the SnakeYaml's Constructor() class. A remote attacker can pass specially crafted yaml content to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
