The (1) S_reghop3, (2) S_reghop4, and (3) S_reghopmaybe3 functions in regexec.c in Perl before 5.24.0 allow context-dependent attackers to cause a denial of service (infinite loop) via crafted utf-8 data, as demonstrated by "a\x80."

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The (1) S_reghop3, (2) S_reghop4, and (3) S_reghopmaybe3 functions in regexec.c in Perl before 5.24.0     allow context-dependent attackers to cause a denial of service (infinite loop) via crafted utf-8 data, as     demonstrated by a\x80. (CVE-2015-8853)

Note that Nessus relies on the presence of the package as reported by the vendor.

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

  - The (1) S_reghop3, (2) S_reghop4, and (3)     S_reghopmaybe3 functions in regexec.c in Perl before     5.24.0 allow context-dependent attackers to cause a     denial of service (infinite loop) via crafted utf-8     data, as demonstrated by 'a\x80.'(CVE-2015-8853)

  - The XSLoader::load method in XSLoader in Perl does not     properly locate .so files when called in a string eval,     which might allow local users to execute arbitrary code     via a Trojan horse library under the current working     directory.(CVE-2016-6185)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3625-1 advisory.

    It was discovered that Perl incorrectly handled certain regular expressions. An attacker could possibly     use this issue to cause Perl to hang, resulting in a denial of service. This issue only affected Ubuntu     14.04 LTS. (CVE-2015-8853)

    It was discovered that Perl incorrectly loaded libraries from the current working directory. A local     attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 14.04     LTS and Ubuntu 16.04 LTS. (CVE-2016-6185)

    It was discovered that Perl incorrectly handled the rmtree and remove_tree functions. A local attacker     could possibly use this issue to set the mode on arbitrary files. This issue only affected Ubuntu 14.04     LTS and Ubuntu 16.04 LTS. (CVE-2017-6512)

    Brian Carpenter 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 has only been addressed in Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2018-6797)

    Nguyen Duc Manh 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. This issue only affected Ubuntu     16.04 LTS and Ubuntu 17.10. (CVE-2018-6798)

    GwanYeong Kim discovered that Perl incorrectly handled certain data when using the pack function. An     attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2018-6913)

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

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

The remote host is affected by the vulnerability described in GLSA-201701-75 (Perl: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Perl. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition, or       escalate privileges.
  Workaround :

    There is no known workaround at this time.
