| Vetor | AV:L/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
util-linux versions prior to 2.22.2
Description
The issue concerns multiple vulnerabilities in the util-linux package that can be exploited locally, potentially leading to breaches of confidentiality, integrity, and availability of protected information. A specific problem in util-linux versions 2.19 and earlier involves the
mount function attempting to append to the /etc/mtab.tmp file without checking for resource limits, which can lead to corruption of the /etc/mtab file if a user triggers the issue with a process that has a small RLIMIT FSIZE value.Recommendations
For util-linux versions prior to 2.22.2, update to version 2.22.2 or later to resolve the issue.
As a temporary workaround, consider restricting access to the
mount function to minimize the risk of exploitation.Correção
