Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU89712

Risk: High

CVSSv4.0: 7.2 [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]

CVE-ID: CVE-2024-33599

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

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.


Mitigation

Update the affected package glibc.

Vulnerable software versions

Slackware Linux: 15.0

glibc-profile: before 2.33

glibc-i18n: before 2.33

glibc: before 2.33

aaa_glibc-solibs: before 2.33

https://www.slackware.com/security/viewer.php?l=slackware-security&y=2024&m=slackware-security.564783


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.

2) NULL pointer dereference

EUVDB-ID: #VU89711

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2024-33600

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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.

Mitigation

Update the affected package glibc.

Vulnerable software versions

Slackware Linux: 15.0

glibc-profile: before 2.33

glibc-i18n: before 2.33

glibc: before 2.33

aaa_glibc-solibs: before 2.33

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) Allocation of Resources Without Limits or Throttling

EUVDB-ID: #VU89710

Risk: Low

CVSSv4.0: 4.3 [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]

CVE-ID: CVE-2024-33601

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

Exploit availability: No

Description

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.

Mitigation

Update the affected package glibc.

Vulnerable software versions

Slackware Linux: 15.0

glibc-profile: before 2.33

glibc-i18n: before 2.33

glibc: before 2.33

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.

4) Buffer overflow

EUVDB-ID: #VU89709

Risk: Medium

CVSSv4.0: 6.6 [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]

CVE-ID: CVE-2024-33602

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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.

Mitigation

Update the affected package glibc.

Vulnerable software versions

Slackware Linux: 15.0

glibc-profile: before 2.33

glibc-i18n: before 2.33
