Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0001 advisory.

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

    The following packages have been upgraded to a later upstream version: rh-perl526-perl (5.26.3), rh-     perl526-perl-Module-CoreList (5.20181130). (BZ#1658969)

    Security Fix(es):

    * perl: Integer overflow leading to buffer overflow in Perl_my_setenv() (CVE-2018-18311)

    * perl: Heap-based buffer overflow in S_handle_regex_sets() (CVE-2018-18312)

    * perl: Heap-based buffer overflow in S_regatom() (CVE-2018-18314)

    * perl: Heap-based buffer read overflow in S_grok_bslash_N() (CVE-2018-18313)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Red Hat would like to thank the Perl project for reporting these issues. Upstream acknowledges Jayakrishna     Menon as the original reporter of CVE-2018-18311; Eiichi Tsukata as the original reporter of     CVE-2018-18312 and CVE-2018-18313; and Jakub Wilk as the original reporter of CVE-2018-18314.

    Please review the referenced CVE identifiers for details.
  Workaround :

    There is no known workaround at this time.

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.4. It is, therefore, affected by multiple vulnerabilities, including:

 - Mounting a maliciously crafted NFS network share may lead to arbitrary code execution with system privileges. (CVE-2019-8508)

 - An application may be able to execute arbitrary code with kernel privileges. (CVE-2019-8529)

 - A malicious application may be able to execute arbitrary code with system privileges (CVE-2019-8549)

This update for perl fixes the following issues :

Secuirty issues fixed :

  - CVE-2018-18311: Fixed integer overflow with oversize     environment (bsc#1114674).

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3834-1 advisory.

    Jayakrishna Menon discovered that Perl incorrectly handled Perl_my_setenv. An attacker could use this     issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2018-18311)

    Eiichi Tsukata discovered that Perl incorrectly handled certain regular expressions. An attacker could use     this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code.
    This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, and Ubuntu 18.10. (CVE-2018-18312)

Multiple vulnerabilities were discovered in the implementation of the Perl programming language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2018-18311     Jayakrishna Menon and Christophe Hauser discovered an     integer overflow vulnerability in Perl_my_setenv leading     to a heap-based buffer overflow with attacker-controlled     input.

  - CVE-2018-18312     Eiichi Tsukata discovered that a crafted regular     expression could cause a heap-based buffer overflow     write during compilation, potentially allowing arbitrary     code execution.

  - CVE-2018-18313     Eiichi Tsukata discovered that a crafted regular     expression could cause a heap-based buffer overflow read     during compilation which leads to information leak.

  - CVE-2018-18314     Jakub Wilk discovered that a specially crafted regular     expression could lead to a heap-based buffer overflow.
