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.
CVE-2017-14166 3 Canonical, Debian, Libarchive 3 Ubuntu Linux, Debian Linux, Libarchive 2025-04-20 4.3 MEDIUM 6.5 MEDIUM
libarchive 3.3.2 allows remote attackers to cause a denial of service (xml_data heap-based buffer over-read and application crash) via a crafted xar archive, related to the mishandling of empty strings in the atol8 function in archive_read_support_format_xar.c.
CVE-2017-15908 2 Canonical, Systemd Project 2 Ubuntu Linux, Systemd 2025-04-20 5.0 MEDIUM 7.5 HIGH
In systemd 223 through 235, a remote DNS server can respond with a custom crafted DNS NSEC resource record to trigger an infinite loop in the dns_packet_read_type_window() function of the 'systemd-resolved' service and cause a DoS of the affected service.
CVE-2016-2378 3 Canonical, Debian, Pidgin 3 Ubuntu Linux, Debian Linux, Pidgin 2025-04-20 6.8 MEDIUM 8.1 HIGH
A buffer overflow vulnerability exists in the handling of the MXIT protocol Pidgin. Specially crafted data sent via the server could potentially result in a buffer overflow, potentially resulting in memory corruption. A malicious server or an unfiltered malicious user can send negative length values to trigger this vulnerability.
CVE-2017-15298 2 Canonical, Git-scm 2 Ubuntu Linux, Git 2025-04-20 4.3 MEDIUM 5.5 MEDIUM
Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of disk consumption; however, an affected process typically would not survive its attempt to build the data structure in memory before writing to disk.
CVE-2016-2148 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2025-04-20 7.5 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to have unspecified impact via vectors involving OPTION_6RD parsing.
CVE-2017-17816 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 use-after-free in pp_getline in asm/preproc.c that will cause a remote denial of service attack.
CVE-2016-1252 2 Canonical, Debian 3 Ubuntu Linux, Advanced Package Tool, Debian Linux 2025-04-20 4.3 MEDIUM 5.9 MEDIUM
The apt package in Debian jessie before 1.0.9.8.4, in Debian unstable before 1.4~beta2, in Ubuntu 14.04 LTS before 1.0.1ubuntu2.17, in Ubuntu 16.04 LTS before 1.2.15ubuntu0.2, and in Ubuntu 16.10 before 1.3.2ubuntu0.1 allows man-in-the-middle attackers to bypass a repository-signing protection mechanism by leveraging improper error handling when validating InRelease file signatures.
CVE-2015-5180 2 Canonical, Gnu 2 Ubuntu Linux, Glibc 2025-04-20 5.0 MEDIUM 7.5 HIGH
res_query in libresolv in glibc before 2.25 allows remote attackers to cause a denial of service (NULL pointer dereference and process crash).
CVE-2017-15281 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2025-04-20 6.8 MEDIUM 8.8 HIGH
ReadPSDImage in coders/psd.c in ImageMagick 7.0.7-6 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file, related to "Conditional jump or move depends on uninitialised value(s)."
CVE-2017-11591 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2025-04-20 5.0 MEDIUM 7.5 HIGH
There is a Floating point exception in the Exiv2::ValueType function in Exiv2 0.26 that will lead to a remote denial of service attack via crafted input.
CVE-2017-13081 7 Canonical, Debian, Freebsd and 4 more 12 Ubuntu Linux, Debian Linux, Freebsd and 9 more 2025-04-20 2.9 LOW 5.3 MEDIUM
Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the group key handshake, allowing an attacker within radio range to spoof frames from access points to clients.
