Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23918)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to improperly imposed security restrictions within the process.mainModule.require() method. A remote user can access non authorized modules.
2) Memory corruption (CVE-ID: CVE-2017-18258)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in the xz_head() function of the GNOME libxml2 library, as defined in the xzlib.c source code due to boundary error in the Lempel-Ziv-Markov (LZMA) decompression feature. A remote unauthenticated attacker can trick the victim into opening a specially crafted LZMA file that submits malicious input, trigger memory corruption and cause the application to crash.
3) Stack-based buffer overflow (CVE-ID: CVE-2017-9048)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper bounds checking in the valid.c code. A remote attacker can send a specially crafted request, trigger stack-based buffer overflow condition and cause the service to crash.
Successful exploitation of the vulnerability results in denial of service.
4) Input validation error (CVE-ID: CVE-2022-32189)
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 in
Float.GobDecode. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2022-36055)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect resource management within the strvals package, responsible for converting strings into Go structures. A remote attacker can pass specially crafted input to the application and consume all available memory on the system.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23920)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to application insecurely loads ICU data through ICU_DATA environment variable with elevated privileges. A remote user can gain access to potentially sensitive information.
