See How to fix? for Debian:9 relevant versions. Note: Versions mentioned in the description apply to the upstream expat package. This is a different vulnerability than CVE-2018-20346.
SQLite before 3.25.3, when the FTS3 extension is enabled, 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 (such as in certain WebSQL use cases).
Upgrade Debian:9 sqlite3 to version 3.16.2-5+deb9u2 or higher. SQLite before 3.25.3, when the FTS3 extension is enabled, 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 (such as in certain WebSQL use cases), aka Magellan. Note: Versions mentioned in the description apply to the upstream sqlite3 package. Upgrade Debian:9 python2.7 to version 2.7.13-2+deb9u4 or higher. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly. that are cached against a given hostname). The impact is: Information disclosure (credentials, cookies, etc.
Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. Note: Versions mentioned in the description apply to the upstream python2.7 package. There is no fixed version for Debian:9 openssl.
Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. This script is distributed by some operating systems in a manner where it is automatically executed. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. Note: Versions mentioned in the description apply to the upstream openssl package.
