CVE-2023-40283 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-05-05 N/A 7.8 HIGH
An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.
CVE-2016-1000338 4 Bouncycastle, Canonical, Netapp and 1 more 5 Legion-of-the-bouncy-castle-java-crytography-api, Ubuntu Linux, 7-mode Transition Tool and 2 more 2025-05-05 5.0 MEDIUM 7.5 HIGH
In Bouncy Castle JCE Provider version 1.55 and earlier the DSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of 'invisible' data into a signed structure.
CVE-2019-3821 2 Canonical, Ceph 2 Ubuntu Linux, Civetweb 2025-05-05 5.0 MEDIUM 7.5 HIGH
A flaw was found in the way civetweb frontend was handling requests for ceph RGW server with SSL enabled. An unauthenticated attacker could create multiple connections to ceph RADOS gateway to exhaust file descriptors for ceph-radosgw service resulting in a remote denial of service.
CVE-2022-44544 2 Canonical, Mahara 2 Ubuntu Linux, Mahara 2025-05-02 N/A 9.8 CRITICAL
Mahara 21.04 before 21.04.7, 21.10 before 21.10.5, 22.04 before 22.04.3, and 22.10 before 22.10.0 potentially allow a PDF export to trigger a remote shell if the site is running on Ubuntu and the flag -dSAFER is not set with Ghostscript.
CVE-2016-1585 1 Canonical 1 Apparmor 2025-05-02 7.5 HIGH 9.8 CRITICAL
In all versions of AppArmor mount rules are accidentally widened when compiled.
CVE-2020-11993 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2025-05-01 4.3 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43 When trace/debug was enabled for the HTTP/2 module and on certain traffic edge patterns, logging statements were made on the wrong connection, causing concurrent use of memory pools. Configuring the LogLevel of mod_http2 above "info" will mitigate this vulnerability for unpatched servers.
CVE-2008-0888 4 Apple, Canonical, Debian and 1 more 4 Mac Os X, Ubuntu Linux, Debian Linux and 1 more 2025-05-01 9.3 HIGH N/A
The NEEDBITS macro in the inflate_dynamic function in inflate.c for unzip can be invoked using invalid buffers, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors that trigger a free of uninitialized or previously-freed data.
CVE-2020-29385 3 Canonical, Fedoraproject, Gnome 3 Ubuntu Linux, Fedora, Gdk-pixbuf 2025-04-29 4.3 MEDIUM 5.5 MEDIUM
GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c->self_code equals 10, self->code_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self->code_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way.
CVE-2018-5733 4 Canonical, Debian, Isc and 1 more 8 Ubuntu Linux, Debian Linux, Dhcp and 5 more 2025-04-25 5.0 MEDIUM 7.5 HIGH
A malicious client which is allowed to send very large amounts of traffic (billions of packets) to a DHCP server can eventually overflow a 32-bit reference counter, potentially causing dhcpd to crash. Affects ISC DHCP 4.1.0 -> 4.1-ESV-R15, 4.2.0 -> 4.2.8, 4.3.0 -> 4.3.6, 4.4.0.
CVE-2024-6387 9 Amazon, Canonical, Debian and 6 more 20 Linux 2023, Ubuntu Linux, Debian Linux and 17 more 2025-04-24 N/A 8.1 HIGH
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
CVE-2024-36390 2 Canonical, Milesight 2 Ubuntu Linux, Devicehub 2025-04-23 N/A 7.5 HIGH
MileSight DeviceHub - CWE-20 Improper Input Validation may allow Denial of Service
CVE-2021-44142 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2025-04-23 9.0 HIGH 8.8 HIGH
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.
CVE-2015-8104 5 Canonical, Debian, Linux and 2 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2025-04-23 4.7 MEDIUM 10.0 CRITICAL
The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c.
CVE-2017-12629 4 Apache, Canonical, Debian and 1 more 5 Solr, Ubuntu Linux, Debian Linux and 2 more 2025-04-20 7.5 HIGH 9.8 CRITICAL
Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.
CVE-2017-17811 2 Canonical, Nasm 2 Ubuntu Linux, Netwide Assembler 2025-04-20 4.3 MEDIUM 5.5 MEDIUM
In Netwide Assembler (NASM) 2.14rc0, there is a heap-based buffer overflow that will cause a remote denial of service attack, related to a strcpy in paste_tokens in asm/preproc.c, a similar issue to CVE-2017-11111.
CVE-2017-14746 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2025-04-20 7.5 HIGH 9.8 CRITICAL
Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request.
CVE-2017-13086 7 Canonical, Debian, Freebsd and 4 more 12 Ubuntu Linux, Debian Linux, Freebsd and 9 more 2025-04-20 5.4 MEDIUM 6.8 MEDIUM
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled Direct-Link Setup (TDLS) Peer Key (TPK) during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.
CVE-2017-8831 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-20 6.9 MEDIUM 6.4 MEDIUM
The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.11.5 allows local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a "double fetch" vulnerability.
CVE-2017-9058 2 Canonical, Ytnef Project 2 Ubuntu Linux, Ytnef 2025-04-20 7.5 HIGH 9.8 CRITICAL
In libytnef in ytnef through 1.9.2, there is a heap-based buffer over-read due to incorrect boundary checking in the SIZECHECK macro in lib/ytnef.c.
CVE-2016-0762 6 Apache, Canonical, Debian and 3 more 15 Tomcat, Ubuntu Linux, Debian Linux and 12 more 2025-04-20 4.3 MEDIUM 5.9 MEDIUM
The Realm implementations in Apache Tomcat versions 9.0.0.M1 to 9.0.0.M9, 8.5.0 to 8.5.4, 8.0.0.RC1 to 8.0.36, 7.0.0 to 7.0.70 and 6.0.0 to 6.0.45 did not process the supplied password if the supplied user name did not exist. This made a timing attack possible to determine valid user names. Note that the default configuration includes the LockOutRealm which makes exploitation of this vulnerability harder.
