"The version of AOS installed on the remote host is prior to 5.19.1.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AOS-5.19.1.5 advisory.

  - Net-SNMP through 5.8 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB
    provides the ability to run arbitrary commands as root. (CVE-2020-15862)

  - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which
    allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single
    backslash character. (CVE-2021-3156)

  - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is
    exploitable by any local user who can execute the sudo command without authentication. Successful
    exploitation of this flaw could lead to privilege escalation.  (CVE-2021-3156)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-
    byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range
    reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when
    passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to
    sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. (CVE-2020-10029)

  - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-
    based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with
    a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to
    sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because
    of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words,
    the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.
    (CVE-2020-29573)

  - Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain
    privileges or cause a denial of service by leveraging improper access to a certain error field.
    (CVE-2020-15436)

  - A flaw incorrect umask during file or directory modification in the Linux kernel NFS (network file system)
    functionality was found in the way user create and delete object using NFSv4.2 or newer if both
    simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with access to
    the NFS could use this flaw to starve the resources causing denial of service. (CVE-2020-35513)

  - 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-2020-10543)

  - 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)

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

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