Description
This security bulletin contains information about 5 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2024-2961)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber
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.
2) Stack-based buffer overflow (CVE-ID: CVE-2024-33599)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
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.
3) NULL pointer dereference (CVE-ID: CVE-2024-33600)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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.
4) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2024-33601)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
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.
5) Buffer overflow (CVE-ID: CVE-2024-33602)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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.
