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.
CVE-2017-13077 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 Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.
CVE-2017-13168 2 Canonical, Google 2 Ubuntu Linux, Android 2025-04-20 4.6 MEDIUM 7.8 HIGH
An elevation of privilege vulnerability in the kernel scsi driver. Product: Android. Versions: Android kernel. Android ID A-65023233.
CVE-2017-9117 2 Canonical, Libtiff 2 Ubuntu Linux, Libtiff 2025-04-20 7.5 HIGH 4.0 MEDIUM
In LibTIFF 4.0.6 and possibly other versions, the program processes BMP images without verifying that biWidth and biHeight in the bitmap-information header match the actual input, as demonstrated by a heap-based buffer over-read in bmp2tiff. NOTE: mentioning bmp2tiff does not imply that the activation point is in the bmp2tiff.c file (which was removed before the 4.0.7 release).
CVE-2017-7645 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2025-04-20 7.8 HIGH 7.5 HIGH
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c.
CVE-2017-17682 3 Canonical, Debian, Imagemagick 3 Ubuntu Linux, Debian Linux, Imagemagick 2025-04-20 7.1 HIGH 6.5 MEDIUM
In ImageMagick 7.0.7-12 Q16, a large loop vulnerability was found in the function ExtractPostscript in coders/wpg.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted wpg image file that triggers a ReadWPGImage call.
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

CVE-2017-7611 3 Canonical, Debian, Elfutils Project 3 Ubuntu Linux, Debian Linux, Elfutils 2025-04-20 4.3 MEDIUM 5.5 MEDIUM
The check_symtab_shndx function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted ELF file.
