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-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-2017-14172 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2025-04-20 7.1 HIGH 6.5 MEDIUM
In coders/ps.c in ImageMagick 7.0.7-0 Q16, a DoS in ReadPSImage() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted PSD file, which claims a large "extent" field in the header but does not contain sufficient backing data, is provided, the loop over "length" would consume huge CPU resources, since there is no EOF check inside the loop.
CVE-2014-9846 5 Canonical, Imagemagick, Opensuse and 2 more 11 Ubuntu Linux, Imagemagick, Leap and 8 more 2025-04-20 7.5 HIGH 9.8 CRITICAL
Buffer overflow in the ReadRLEImage function in coders/rle.c in ImageMagick 6.8.9.9 allows remote attackers to have unspecified impact.
CVE-2017-17669 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2025-04-20 4.3 MEDIUM 5.5 MEDIUM
There is a heap-based buffer over-read in the Exiv2::Internal::PngChunk::keyTXTChunk function of pngchunk_int.cpp in Exiv2 0.26. A crafted PNG file will lead to a remote denial of service attack.
CVE-2017-10686 2 Canonical, Nasm 2 Ubuntu Linux, Netwide Assembler 2025-04-20 6.8 MEDIUM 7.8 HIGH
In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free vulnerabilities in the tool nasm. The related heap is allocated in the token() function and freed in the detoken() function (called by pp_getline()) - it is used again at multiple positions later that could cause multiple damages. For example, it causes a corrupted double-linked list in detoken(), a double free or corruption in delete_Token(), and an out-of-bounds write in detoken(). It has a high possibility to lead to a remote code execution attack.
CVE-2017-14494 5 Canonical, Debian, Novell and 2 more 7 Ubuntu Linux, Debian Linux, Leap and 4 more 2025-04-20 4.3 MEDIUM 5.9 MEDIUM
dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests.
CVE-2017-16527 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-20 7.2 HIGH 6.6 MEDIUM
sound/usb/mixer.c in the Linux kernel before 4.13.8 allows local users to cause a denial of service (snd_usb_mixer_interrupt use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device.
CVE-2017-14864 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2025-04-20 4.3 MEDIUM 5.5 MEDIUM
An Invalid memory address dereference was discovered in Exiv2::getULong in types.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.
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-2017-16525 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-20 7.2 HIGH 6.6 MEDIUM
The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel before 4.13.8 allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup.
