Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Buffer overflow
EUVDB-ID: #VU88822
Risk: High
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2024-2961
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: Yes
DescriptionThe 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.
MitigationUpdate the affected packages.
sys-libs/glibc to version: 2.38-r13
Gentoo Linux: All versions
sys-libs/glibc: before 2.38-r13

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Stack-based buffer overflow
EUVDB-ID: #VU89712
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-33599
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe 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.
Update the affected packages.
sys-libs/glibc to version: 2.38-r13
Gentoo Linux: All versions
sys-libs/glibc: before 2.38-r13

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) NULL pointer dereference
EUVDB-ID: #VU89711
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-33600
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages.
sys-libs/glibc to version: 2.38-r13
Gentoo Linux: All versions
sys-libs/glibc: before 2.38-r13
External linkshttp://security.gentoo.org/glsa/202405-17
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Allocation of Resources Without Limits or Throttling
EUVDB-ID: #VU89710
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-33601
CWE-ID:
CWE-770 - Allocation of Resources Without Limits or Throttling
Exploit availability: No
DescriptionThe 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.
Update the affected packages.
sys-libs/glibc to version: 2.38-r13
Gentoo Linux: All versions
sys-libs/glibc: before 2.38-r13
External linkshttp://security.gentoo.org/glsa/202405-17
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
5) Buffer overflow
EUVDB-ID: #VU89709
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-33602
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe 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.
