A heap-buffer-overflow was discovered in BusyBox v.1.36.1 in the next_token function at awk.c:1159.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0021 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2023-42365:
    A use-after-free vulnerability in BusyBox v.1.36.1 allows attackers to cause a denial of service via a     crafted awk pattern in the awk.c evaluate function.

    CVE-2023-42366:
    A use-after-free vulnerability was discovered in BusyBox v.1.36.1 via a crafted awk pattern in the awk.c     copyvar function.

    CVE-2023-42364:
    A heap-buffer-overflow was discovered in BusyBox v.1.36.1 in the next_token function at awk.c:1159.

    CVE-2023-42363:
    A use-after-free vulnerability was discovered in xasprintf function in xfuncs_printf.c:344 in BusyBox     v.1.36.1.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.
