"The remote NewStart CGSL host, running version MAIN 6.06, has glibc packages installed that are affected by multiple
vulnerabilities:

  - The mq_notify function in the GNU C Library (aka glibc) versions 2.32 and 2.33 has a use-after-free. It
    may use the notification thread attributes object (passed through its struct sigevent parameter) after it
    has been freed by the caller, leading to a denial of service (application crash) or possibly unspecified
    other impact. (CVE-2021-33574)

  - elf/dl-load.c in the GNU C Library (aka glibc or libc6) 2.19 through 2.26 mishandles RPATH and RUNPATH
    containing $ORIGIN for a privileged (setuid or AT_SECURE) program, which allows local users to gain
    privileges via a Trojan horse library in the current working directory, related to the fillin_rpath and
    decompose_rpath functions. This is associated with misinterpretion of an empty RPATH/RUNPATH token as the
    ./ directory. NOTE: this configuration of RPATH/RUNPATH for a privileged program is apparently very
    uncommon; most likely, no such program is shipped with any common Linux distribution. (CVE-2017-16997)

  - The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple
    suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite
    loop when processing invalid multi-byte input sequences, leading to a denial of service. (CVE-2016-10228)

  - The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to
    cause a denial of service (out-of-bounds read and crash) via 64 bytes of input. (CVE-2016-6261)

  - The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent
    attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data.
    (CVE-2016-6263)

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