CVE-2019-19959 2 Canonical, Sqlite 2 Ubuntu Linux, Sqlite 2026-10-14 5.0 MEDIUM 7.5 HIGH
ext/misc/zipfile.c in SQLite 3.30.1 mishandles certain uses of INSERT INTO in situations involving embedded '\0' characters in filenames, leading to a memory-management error that can be detected by (for example) valgrind.
CVE-2019-19956 7 Canonical, Debian, Fedoraproject and 4 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs.
CVE-2019-19906 8 Apache, Apple, Canonical and 5 more 20 Bookkeeper, Ipados, Iphone Os and 17 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.
CVE-2019-9948 6 Canonical, Debian, Fedoraproject and 3 more 11 Ubuntu Linux, Debian Linux, Fedora and 8 more 2026-10-14 6.4 MEDIUM 9.1 CRITICAL
urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call.
CVE-2019-9674 3 Canonical, Netapp, Python 3 Ubuntu Linux, Active Iq Unified Manager, Python 2026-10-14 5.0 MEDIUM 7.5 HIGH
Lib/zipfile.py in Python through 3.7.2 allows remote attackers to cause a denial of service (resource consumption) via a ZIP bomb.
CVE-2019-9636 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2026-10-14 5.0 MEDIUM 9.8 CRITICAL
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. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. 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. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.
CVE-2019-9169 4 Canonical, Gnu, Mcafee and 1 more 6 Ubuntu Linux, Glibc, Web Gateway and 3 more 2026-10-14 7.5 HIGH 9.8 CRITICAL
In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-based buffer over-read via an attempted case-insensitive regular-expression match.
CVE-2019-8457 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2026-10-14 7.5 HIGH 9.8 CRITICAL
SQLite3 from 3.6.0 to and including 3.27.2 is vulnerable to heap out-of-bound read in the rtreenode() function when handling invalid rtree tables.
CVE-2019-6111 10 Apache, Canonical, Debian and 7 more 27 Mina Sshd, Ubuntu Linux, Debian Linux and 24 more 2026-10-14 5.8 MEDIUM 5.9 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well (for example, to overwrite the .ssh/authorized_keys file).
CVE-2019-6109 9 Canonical, Debian, Fedoraproject and 6 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2026-10-14 4.0 MEDIUM 6.8 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
CVE-2019-5188 6 Canonical, Debian, E2fsprogs Project and 3 more 8 Ubuntu Linux, Debian Linux, E2fsprogs and 5 more 2026-10-14 4.4 MEDIUM 7.5 HIGH
A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
CVE-2019-5094 5 Canonical, Debian, E2fsprogs Project and 2 more 6 Ubuntu Linux, Debian Linux, E2fsprogs and 3 more 2026-10-14 4.6 MEDIUM 7.5 HIGH
An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
CVE-2019-5018 2 Canonical, Sqlite 2 Ubuntu Linux, Sqlite 2026-10-14 6.8 MEDIUM 8.1 HIGH
An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
CVE-2019-19244 4 Canonical, Oracle, Siemens and 1 more 4 Ubuntu Linux, Mysql Workbench, Sinec Infrastructure Network Services and 1 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
sqlite3Select in select.c in SQLite 3.30.1 allows a crash if a sub-select uses both DISTINCT and window functions, and also has certain ORDER BY usage.
CVE-2019-19242 5 Canonical, Oracle, Redhat and 2 more 5 Ubuntu Linux, Mysql Workbench, Enterprise Linux and 2 more 2026-10-14 4.3 MEDIUM 5.9 MEDIUM
SQLite 3.30.1 mishandles pExpr->y.pTab, as demonstrated by the TK_COLUMN case in sqlite3ExprCodeTarget in expr.c.
CVE-2019-19126 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2026-10-14 2.1 LOW 3.3 LOW
On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program.
CVE-2019-16168 8 Canonical, Debian, Fedoraproject and 5 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2026-10-14 4.3 MEDIUM 6.5 MEDIUM
In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application because of missing validation of a sqlite_stat1 sz field, aka a "severe division by zero in the query planner."
CVE-2019-16056 7 Canonical, Debian, Fedoraproject and 4 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2026-10-14 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An application that uses the email module and implements some kind of checks on the From/To headers of a message could be tricked into accepting an email address that should be denied. An attack may be the same as in CVE-2019-11340; however, this CVE applies to Python more generally.
CVE-2019-13627 4 Canonical, Debian, Libgcrypt20 Project and 1 more 4 Ubuntu Linux, Debian Linux, Libgcrypt20 and 1 more 2026-10-14 2.6 LOW 6.3 MEDIUM
It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.
