Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for libxml2 fixes the following security issues :

CVE-2018-9251: The xz_decomp function allowed remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint (bsc#1088279).

CVE-2018-14567: Prevent denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint (bsc#1105166).

CVE-2018-14404: Prevent NULL pointer dereference in the xmlXPathCompOpEval() function when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case leading to a denial of service attack (bsc#1102046).

CVE-2017-18258: The xz_head function allowed remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality did not restrict memory usage to what is required for a legitimate file (bsc#1088601).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
