Alpine: multiple libxml2 packages, multiple py3-libxml2 packages: security update to 2.9.8-r0 (deprecated)

high Tenable Cloud Security Plugin ID 400662

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2
through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case.
Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable
to a denial of service attack due to a crash of the application. (CVE-2018-14404)

- 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)
