Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Insufficient Entropy (CVE-ID: CVE-2021-4238)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient entropy when generating alphanumeric strings within RandomAlphaNumeric and CryptoRandomAlphaNumeric functions, which always return strings containing at least one digit from 0 to 9. A remote attacker can launch brute-force attacks and gain access to sensitive information.
2) Resource exhaustion (CVE-ID: CVE-2022-3064)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing large YAML documents. A remote attacker can consume excessive amounts of CPU or memory and perform a denial of service (DoS) attack.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23947)
The vulnerability allows a remote user to compromise the entire cluster.
The vulnerability exists due to missing authorization checks when updating passwords. A remote user with ability to update at least one cluster secret can update any cluster secret.
4) Integer overflow (CVE-ID: CVE-2022-23521)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied input when parsing the .gitattributes attributes. A remote attacker can trick the victim into cloning a specially crafted repository and execute arbitrary code on the system.
5) Integer overflow (CVE-ID: CVE-2022-40303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in parse.c when processing content when XML_PARSE_HUGE is set. A remote attacker can pass specially crafted data to the application, 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.
6) Resource management error (CVE-ID: CVE-2022-40304)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in entities.c due to the way libxml2 handles reference cycles. The library does not anticipate that entity content can be allocated from a dict and clears it upon reference cycle detection by setting its first byte to zero. This can lead to memory corruption issues, such as double free errors and result in a denial of service.
7) Heap-based buffer overflow (CVE-ID: CVE-2022-41903)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error during git archive invocation. A remote attacker can trick the victim into using the application against a specially crafted archive, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Integer overflow (CVE-ID: CVE-2022-47629)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the CRL signature parser. A remote attacker can pass specially crafted data to the application, 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.
