Published: 2021-03-12 07:23:52
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/Au:N/C:P/I:N/A:P

Summary:
The remote host is missing an update for the Huawei EulerOS 'perl-DBI' Linux Distribution Package(s) announced via the EulerOS-SA-2021-1622 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference.(CVE-2019-20919) An issue was discovered in the DBI module through 1.643 for Perl. DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute in the data source name (DSN). NOTE: this issue exists because of an incomplete fix for CVE-2014-10401.(CVE-2014-10402) An untrusted pointer dereference flaw was found in Perl-DBI 1.643. A local attacker who is able to manipulate calls to dbd_db_login6_sv() could cause memory corruption, affecting the service's availability.(CVE-2020-14392) A buffer overflow was found in perl-DBI 1.643 in DBI.xs. A local attacker who is able to supply a string longer than 300 characters could cause an out-of-bounds write, affecting the availability of the service or integrity of data.(CVE-2020-14393)

Affected Versions:
'perl-DBI' Linux Distribution Package(s) on Huawei EulerOS Virtualization release 2.9.1.

Recommendations:
Please install the updated Linux Distribution Package(s).

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
