Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of libxml2 installed on the remote host is prior to 2.9.1-6. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1848 advisory.A flaw was found in the libxml2 library in functions used to manipulate the xmlBuf and the xmlBuffer types. A substantial input causes values to calculate buffer sizes to overflow, resulting in an out-of- bounds write. (CVE-2022-29824)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
