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 version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2023-0808 advisory.

  - The go command may execute arbitrary code at build time when using cgo. This may occur when running go     get on a malicious module, or when running any other command which builds untrusted code. This is can by     triggered by linker flags, specified via a #cgo LDFLAGS directive. Flags containing embedded spaces are     mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in     the argument of another flag. This only affects usage of the gccgo compiler. (CVE-2023-29405)

  - When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by     finalizing the operation with a rename from a temporary name to the final target file name.In that rename     operation, it might accidentally *widen* the permissions for the target file, leaving the updated file     accessible to more users than intended. (CVE-2022-32207)

  - decode-uri-component 0.2.0 is vulnerable to Improper Input Validation resulting in DoS. (CVE-2022-38900)

  - The got package before 12.1.0 (also fixed in 11.8.5) for Node.js allows a redirect to a UNIX socket.
    (CVE-2022-33987)

  - Prototype pollution vulnerability in function parseQuery in parseQuery.js in webpack loader-utils via the     name variable in parseQuery.js. This affects all versions prior to 1.4.1 and 2.0.3. (CVE-2022-37601)

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