A Segmentation Fault issue discovered in in ieee_segment function in outieee.c in nasm 2.14.03 and 2.15 allows remote attackers to cause a denial of service via crafted assembly file.

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-2024:0040 advisory.

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

    CVE-2020-21528:
    A Segmentation Fault issue discovered in in ieee_segment function in outieee.c in nasm 2.14.03 and 2.15     allows remote attackers to cause a denial of service via crafted assembly file.

    CVE-2022-44370:
    NASM v2.16 was discovered to contain a heap buffer overflow in the component quote_for_pmake()     asm/nasm.c:856

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A Segmentation Fault issue discovered in in ieee_segment function in outieee.c in nasm 2.14.03 and 2.15     allows remote attackers to cause a denial of service via crafted assembly file. (CVE-2020-21528)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the versions of the nasm packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A Segmentation Fault issue discovered in in ieee_segment function in outieee.c in nasm 2.14.03 and 2.15     allows remote attackers to cause a denial of service via crafted assembly file. (CVE-2020-21528)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-202312-09 (NASM: Multiple Vulnerabilities)
