The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:1678 advisory.

  - perl: heap-based buffer overflow in regular expression compiler leads to DoS (CVE-2020-10543)

  - perl: corruption of intermediate language state of compiled regular expression due to integer overflow     leads to DoS (CVE-2020-10878)

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

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0012 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2020-10543:
    Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular     expression quantifiers have an integer overflow.

    CVE-2020-10878:
    Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING     situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction     injection.

    CVE-2020-12723:
    regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of     recursive S_study_chunk calls.

Tenable has extracted the preceding description block directly from the Alibaba Cloud 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.

  - Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING     situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction     injection. (CVE-2020-10878)

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

The version of AOS installed on the remote host is prior to 5.15.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.15.6 advisory.

  - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write     access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character     sequence. (CVE-2021-26937)

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition. Successful attacks require human     interaction from a person other than the attacker. Successful attacks of this vulnerability can result in     unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded,     Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments     that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox     for security. (CVE-2021-2163)

  - In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - In create_pinctrl of core.c, there is a possible out of bounds read due to a use after free. This could     lead to local information disclosure with no additional execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-140550171     (CVE-2020-0427)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)
