Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2024-4540)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to an error in the OAuth 2.0 Pushed Authorization Requests (PAR) implementation. Client provided parameters are included in plain text in to
the KC_RESTART cookie returned by the authorization server's HTTP
response to a request_uri authorization request. A local user with access to the system can use the cookie to gain access to sensitive information.
2) Buffer overflow (CVE-ID: CVE-2024-2961)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the iconv() function when converting string to the ISO-2022-CN-EXT character set. A remote attacker can pass specially crafted input to the application, trigger a 4 byte buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Improper input validation (CVE-ID: CVE-2024-21011)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the Hotspot component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
4) Improper input validation (CVE-ID: CVE-2024-21012)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Networking component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
5) Improper input validation (CVE-ID: CVE-2024-21068)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Hotspot component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
6) Improper input validation (CVE-ID: CVE-2024-21094)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Hotspot component in Oracle GraalVM Enterprise Edition. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
7) Stack-based buffer overflow (CVE-ID: CVE-2024-33599)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in nscd binary. A remote unauthenticated attacker can exhaust the nscd fixed size cache to trigger a stack-based buffer overflow and execute arbitrary code on the target system.
8) NULL pointer dereference (CVE-ID: CVE-2024-33600)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error when nscd cache fails to add a not-found netgroup response to the cache. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
9) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2024-33601)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The
vulnerability exists due to the Name Service Cache Daemon (nscd) can terminate the service during its startup. A local use can perform a denial of service (DoS) attack.
10) Buffer overflow (CVE-ID: CVE-2024-33602)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to netgroup cache assumes NSS callback is using in-buffer strings in nscd binary. A remote attacker can trigger memory corruption and perform a denial of service (DoS) attack.
