The remote NewStart CGSL host, running version MAIN 6.02, has perl packages installed that are affected by multiple vulnerabilities:

  - 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)

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

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

  - Perl might allow context-dependent attackers to bypass     the taint protection mechanism in a child process via     duplicate environment variables in envp.(CVE-2016-2381)

  - 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 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 Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1678 advisory.

    Perl is a high-level programming language that is commonly used for system administration utilities and     web programming.

    Security Fix(es):

    * 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)
