Published: 2020-08-23 03:00:23
CVE Author: NIST National Vulnerability Database

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

Summary:
The remote host is missing an update for the 'sqlite3' Linux Distribution Package(s) announced via the DLA-2340-1 advisory.

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

Technical Details:
Several vulnerabilities have been discovered in sqlite3, a C library that implements an SQL database engine. CVE-2018-8740 Databases whose schema is corrupted using a CREATE TABLE AS statement could cause a NULL pointer dereference. CVE-2018-20346 When the FTS3 extension is enabled, sqlite3 encounters an integer overflow (and resultant buffer overflow) for FTS3 queries that occur after crafted changes to FTS3 shadow tables, allowing remote attackers to execute arbitrary code by leveraging the ability to run arbitrary SQL statements. CVE-2018-20506 When the FTS3 extension is enabled, sqlite3 encounters an integer overflow (and resultant buffer overflow) for FTS3 queries in a 'merge' operation that occurs after crafted changes to FTS3 shadow tables, allowing remote attackers to execute arbitrary code by leveraging the ability to run arbitrary SQL statements CVE-2019-5827 Integer overflow allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page, primarily impacting chromium. CVE-2019-9936 Running fts5 prefix queries inside a transaction could trigger a heap-based buffer over-read, which may lead to an information leak. CVE-2019-9937 Interleaving reads and writes in a single transaction with an fts5 virtual table will lead to a NULL Pointer Dereference. CVE-2019-16168 A browser or other application can be triggered to crash because of inadequate parameter validation which could lead to a divide-by-zero error. CVE-2019-20218 WITH stack unwinding proceeds even after a parsing error, resulting in a possible application crash. CVE-2020-13630 The code related to the snippet feature exhibits a use-after-free defect. CVE-2020-13632 A crafted matchinfo() query can lead to a NULL pointer dereference. CVE-2020-13871 The parse tree rewrite for window functions is too late, leading to a use-after-free defect. CVE-2020-11655 An improper initialization of AggInfo objects allows attackers to cause a denial of service (segmentation fault) via a malformed window-function query. CVE-2020-13434 The code in sqlite3_str_vappendf in printf.c contains an integer overflow defect.

Affected Versions:
'sqlite3' Linux Distribution Package(s) on Debian Linux.

Recommendations:
For Debian 9 stretch, these problems have been fixed in version 3.16.2-5+deb9u2. We recommend that you upgrade your sqlite3 Linux Distribution Packages.

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".
