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

  - pcregrep in PCRE before 8.38 mishandles the -q option     for binary files, which might allow remote attackers to     obtain sensitive information via a crafted file, as     demonstrated by a CGI script that sends stdout data to     a client.(CVE-2015-8393)

  - Stack-based buffer overflow in the     pcre32_copy_substring function in pcre_get.c in     libpcre1 in PCRE 8.40 allows remote attackers to cause     a denial of service (WRITE of size 4) or possibly have     unspecified other impact via a crafted     file.(CVE-2017-7245)

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 SUSE Linux SLED12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3652-1 advisory.

  - The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680     (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds     read and application crash) via a crafted regular expression. (CVE-2017-6004)

  - libpcre1 in PCRE 8.40 and libpcre2 in PCRE2 10.23 allow remote attackers to cause a denial of service     (segmentation violation for read access, and application crash) by triggering an invalid Unicode property     lookup. (CVE-2017-7186)

  - The _pcre32_xclass function in pcre_xclass.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a     denial of service (invalid memory read) via a crafted file. (CVE-2017-7244)

  - Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40     allows remote attackers to cause a denial of service (WRITE of size 4) or possibly have unspecified other     impact via a crafted file. (CVE-2017-7245)

  - Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40     allows remote attackers to cause a denial of service (WRITE of size 268) or possibly have unspecified     other impact via a crafted file. (CVE-2017-7246)

  - libpcre in PCRE before 8.43 allows a subject buffer over-read in JIT when UTF is disabled, and \X or \R     has more than one fixed quantifier, a related issue to CVE-2019-20454. (CVE-2019-20838)

  - libpcre in PCRE before 8.44 allows an integer overflow via a large number after a (?C substring.
    (CVE-2020-14155)

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

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.

  - pcre: stack-based buffer overflow write in pcre32_copy_substring (CVE-2017-7246)

  - In PCRE 8.41, the OP_KETRMAX feature in the match function in pcre_exec.c allows stack exhaustion     (uncontrolled recursion) when processing a crafted regular expression. (CVE-2017-11164)

  - The compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE through 8.x before revision 1680     (e.g., the PHP 7.1.1 bundled version) allows remote attackers to cause a denial of service (out-of-bounds     read and application crash) via a crafted regular expression. (CVE-2017-6004)

  - libpcre1 in PCRE 8.40 and libpcre2 in PCRE2 10.23 allow remote attackers to cause a denial of service     (segmentation violation for read access, and application crash) by triggering an invalid Unicode property     lookup. (CVE-2017-7186)

  - The _pcre32_xclass function in pcre_xclass.c in libpcre1 in PCRE 8.40 allows remote attackers to cause a     denial of service (invalid memory read) via a crafted file. (CVE-2017-7244)

  - Stack-based buffer overflow in the pcre32_copy_substring function in pcre_get.c in libpcre1 in PCRE 8.40     allows remote attackers to cause a denial of service (WRITE of size 4) or possibly have unspecified other     impact via a crafted file. (CVE-2017-7245)

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 host is affected by the vulnerability described in GLSA-201710-25 (PCRE: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in The PCRE Library.
      Please review the references below for details.
  Impact :

    A remote attacker could possibly cause a Denial of Service condition or       other unspecified impacts via a specially crafted file.
  Workaround :

    There is no known workaround at this time.
