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

  - An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the     XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to     access an array at a negative 2GB offset, typically leading to a segmentation fault. (CVE-2022-40303)

  - An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a     hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be     provoked. (CVE-2022-40304)

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

    There's a flaw in libxml2's xmllint. An attacker who is able to submit a crafted file to be processed by     xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity,     and availability. (CVE-2021-3516)

    There is a flaw in the xml entity encoding functionality of libxml2. An attacker who is able to supply a     crafted file to be processed by an application linked with the affected functionality of libxml2 could     trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with     some potential impact to confidentiality and integrity if an attacker is able to use memory information to     further exploit the application. (CVE-2021-3517)

    There's a flaw in libxml2. An attacker who is able to submit a crafted file to be processed by an     application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to     confidentiality, integrity, and availability. (CVE-2021-3518)

    A NULL pointer dereference flaw was found in libxml2, where it did not propagate errors while parsing XML     mixed content. This flaw causes the application to crash if an untrusted XML document is parsed in     recovery mode and post validated. The highest threat from this vulnerability is to system availability.
    (CVE-2021-3537)

    A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing     protection mechanisms and leading to denial of service. (CVE-2021-3541)
