Integer underflow in regcomp.c in Perl before 5.20, as used in Apple OS X before 10.10.5 and other products, allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a long digit string associated with an invalid backreference within a regular expression.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - perl: heap buffer overflow in pp_pack.c (CVE-2018-6913)

  - Perl 5.10.x allows context-dependent attackers to cause a denial of service (NULL pointer dereference and     application crash) by leveraging an ability to inject arguments into a (1) getpeername, (2) readdir, (3)     closedir, (4) getsockname, (5) rewinddir, (6) tell, or (7) telldir function call. (CVE-2011-0761)

  - _is_safe in the File::Temp module for Perl does not properly handle symlinks. (CVE-2011-4116)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - perl: XSLoader loads relative paths not included in @INC (CVE-2016-6185)

  - The Dumper method in Data::Dumper before 2.154, as used in Perl 5.20.1 and earlier, allows context-     dependent attackers to cause a denial of service (stack consumption and crash) via an Array-Reference with     many nested Array-References, which triggers a large number of recursive calls to the DD_dump function.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2916-1 advisory.

    It was discovered that Perl incorrectly handled certain regular expressions with an invalid backreference.
    An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2013-7422)

    Markus Vervier discovered that Perl incorrectly handled nesting in the Data::Dumper module. An attacker     could use this issue to cause Perl to consume memory and crash, resulting in a denial of service.
    (CVE-2014-4330)

    Stephane Chazelas discovered that Perl incorrectly handled duplicate environment variables. An attacker     could possibly use this issue to bypass the taint protection mechanism. (CVE-2016-2381)

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