This update for libxml2 fixes the following issues: Security issues fixed :

  - CVE-2017-9050: heap-based buffer overflow     (xmlDictAddString func) [bsc#1039069, bsc#1039661]

  - CVE-2017-9049: heap-based buffer overflow     (xmlDictComputeFastKey func) [bsc#1039066]

  - CVE-2017-9047: stack overflow vulnerability     (xmlSnprintfElementContent func) [bsc#1039064] A     clarification for the previously released update: For     CVE-2016-9318 we decided not to ship a fix since it can     break existing setups. Please take appropriate actions     if you parse untrusted XML files and use the new

-noxxe flag if possible (bnc#1010675, bnc#1013930).

According to the versions of the libxml2 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a     heap-based buffer over-read in the xmlDictAddString     function in dict.c. This vulnerability causes programs     that use libxml2, such as PHP, to crash. This     vulnerability exists because of an incomplete fix for     CVE-2016-1839.(CVE-2017-9050)

  - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a     heap-based buffer over-read in the     xmlDictComputeFastKey function in dict.c. This     vulnerability causes programs that use libxml2, such as     PHP, to crash. This vulnerability exists because of an     incomplete fix for libxml2 Bug 759398.(CVE-2017-9049)

  - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a     stack-based buffer overflow. The function     xmlSnprintfElementContent in valid.c is supposed to     recursively dump the element content definition into a     char buffer 'buf' of size 'size'. At the end of the     routine, the function may strcat two more characters     without checking whether the current strlen(buf) + 2 <     size. This vulnerability causes programs that use     libxml2, such as PHP, to crash.(CVE-2017-9048)

  - The htmlParseTryOrFinish function in HTMLparser.c in     libxml2 2.9.4 allows attackers to cause a denial of     service (buffer over-read) or information     disclosure.(CVE-2017-8872)

  - The xz_decomp function in xzlib.c in libxml2 2.9.8, if
    --with-lzma is used, allows remote attackers to cause a     denial of service (infinite loop) via a crafted XML     file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated     by xmllint, a different vulnerability than     CVE-2015-8035.(CVE-2018-9251)

  - libxml2 2.9.8, if --with-lzma is used, allows remote     attackers to cause a denial of service (infinite loop)     via a crafted XML file that triggers     LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a     different vulnerability than CVE-2015-8035 and     CVE-2018-9251.(CVE-2018-14567)

This update for libxml2 fixes the following security issues :

  - CVE-2017-9050: A heap-based buffer over-read in     xmlDictAddString (bsc#1039069, bsc#1039661)

  - CVE-2017-9049: A heap-based buffer overflow in     xmlDictComputeFastKey (bsc#1039066)

  - CVE-2017-9048: A stack overflow vulnerability in     xmlSnprintfElementContent (bsc#1039063)

  - CVE-2017-9047: A stack overflow vulnerability in     xmlSnprintfElementContent (bsc#1039064)

This update was imported from the SUSE:SLE-12-SP2:Update update project.

The remote host is affected by the vulnerability described in GLSA-201711-01 (libxml2: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in libxml2. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker, by enticing a user to process a specially crafted XML       document, could remotely execute arbitrary code, conduct XML External       Entity (XXE) attacks, or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.2.2. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2023-23 advisory. Several of the third-party components were found to contain vulnerabilities, and updated versions have been made available by the providers. Out of caution and in line with best practice, Tenable has opted to upgrade these components to address the potential impact of the issues. Nessus Network Monitor 6.2.2 updates the following components:

  - c-ares from version 1.10.0 to version 1.19.1.
  - curl from version 7.79.1 to version 8.1.2.
  - libbzip2 from version 1.0.6 to version 1.0.8.
  - libpcre from version 8.42 to version 8.44.
  - libxml2 from version 2.7.7 to version 2.11.1.
  - libxslt from version 1.1.26 to version 1.1.37.
  - libxmlsec from version 1.2.18 to version 1.2.37.
  - sqlite from version 3.27.2 to version 3.40.1.
  - jQuery Cookie from version 1.3.1 to version 1.4.1.
  - jQuery UI from version 1.13.0 to version 1.13.2.
  - OpenSSL from version 3.0.8 to version 3.0.9.

This update for libxml2 fixes the following issues :

  - CVE-2017-9047, CVE-2017-9048: The function     xmlSnprintfElementContent in valid.c was vulnerable to a     stack-based buffer overflow (bsc#1039063, bsc#1039064)

  - CVE-2017-9049: The function xmlDictComputeFastKey in     dict.c was vulnerable to a heap-based buffer over-read.
    (bsc#1039066)

  - CVE-2017-9050: The function xmlDictAddString was     vulnerable to a heap-based buffer over-read     (bsc#1039661)

  - CVE-2016-1839: heap-based buffer overflow     (xmlDictAddString func) (bnc#1039069)

The CentOS Linux 7.9 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0710 advisory.

    This advisory aggregates security fixes for the libxml2 SRPM in CIQ CentOS Bridge 7.9. It addresses 15     CVEs: CVE-2024-25062, CVE-2023-39615, CVE-2017-9048, CVE-2017-0663, CVE-2017-9050, and 10 more.

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

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

According to the versions of the libxml2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An integer overflow in xmlmemory.c in libxml2 before     2.9.5, as used in Google Chrome prior to 62.0.3202.62     and other products, allowed a remote attacker to     potentially exploit heap corruption via a crafted XML     file.(CVE-2017-5130)

  - libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a     heap-based buffer over-read in the     xmlDictComputeFastKey function in dict.c. This     vulnerability causes programs that use libxml2, such as     PHP, to crash. (CVE-2017-9049)

  - A flaw in libxml2 allows remote XML entity inclusion     with default parser flags (i.e., when the caller did     not request entity substitution, DTD validation,     external DTD subset loading, or default DTD     attributes). Depending on the context, this may expose     a higher-risk attack surface in libxml2 not usually     reachable with default parser flags, and expose content     from local files, HTTP, or FTP servers (which might be     otherwise unreachable).(CVE-2017-7375)

  - Buffer overflow in libxml2 allows remote attackers to     execute arbitrary code by leveraging an incorrect limit     for port values when handling redirects.(CVE-2017-7376)
