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.

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

  - 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)

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

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 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.
