CVE-2007-2583 3 Canonical, Debian, Oracle 3 Ubuntu Linux, Debian Linux, Mysql 2021-11-08 4.0 MEDIUM N/A
The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40, and 5.1 before 5.1.18-beta, allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference.
CVE-2020-11933 1 Canonical 2 Snapd, Ubuntu Linux 2021-11-04 4.6 MEDIUM 6.8 MEDIUM
cloud-init as managed by snapd on Ubuntu Core 16 and Ubuntu Core 18 devices was run without restrictions on every boot, which a physical attacker could exploit by crafting cloud-init user-data/meta-data via external media to perform arbitrary changes on the device to bypass intended security mechanisms such as full disk encryption. This issue did not affect traditional Ubuntu systems. Fixed in snapd version 2.45.2, revision 8539 and core version 2.45.2, revision 9659.
CVE-2019-9506 8 Apple, Blackberry, Canonical and 5 more 274 Iphone Os, Mac Os X, Tvos and 271 more 2021-11-04 4.8 MEDIUM 8.1 HIGH
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.
CVE-2019-10131 5 Canonical, Debian, Imagemagick and 2 more 5 Ubuntu Linux, Debian Linux, Imagemagick and 2 more 2021-10-28 3.6 LOW 7.1 HIGH
An off-by-one read vulnerability was discovered in ImageMagick before version 7.0.7-28 in the formatIPTCfromBuffer function in coders/meta.c. A local attacker may use this flaw to read beyond the end of the buffer or to crash the program.
CVE-2019-10192 5 Canonical, Debian, Oracle and 2 more 10 Ubuntu Linux, Debian Linux, Communications Operations Monitor and 7 more 2021-10-28 6.5 MEDIUM 7.2 HIGH
A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By carefully corrupting a hyperloglog using the SETRANGE command, an attacker could trick Redis interpretation of dense HLL encoding to write up to 3 bytes beyond the end of a heap-allocated buffer.
CVE-2019-10193 5 Canonical, Debian, Oracle and 2 more 9 Ubuntu Linux, Debian Linux, Communications Operations Monitor and 6 more 2021-10-28 6.5 MEDIUM 7.2 HIGH
A stack-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By corrupting a hyperloglog using the SETRANGE command, an attacker could cause Redis to perform controlled increments of up to 12 bytes past the end of a stack-allocated buffer.
CVE-2021-3710 1 Canonical 2 Apport, Ubuntu Linux 2021-10-08 4.7 MEDIUM 5.5 MEDIUM
An information disclosure via path traversal was discovered in apport/hookutils.py function read_file(). This issue affects: apport 2.14.1 versions prior to 2.14.1-0ubuntu3.29+esm8; 2.20.1 versions prior to 2.20.1-0ubuntu2.30+esm2; 2.20.9 versions prior to 2.20.9-0ubuntu7.26; 2.20.11 versions prior to 2.20.11-0ubuntu27.20; 2.20.11 versions prior to 2.20.11-0ubuntu65.3;
CVE-2019-3820 3 Canonical, Gnome, Opensuse 3 Ubuntu Linux, Gnome-shell, Leap 2021-09-29 4.6 MEDIUM 4.3 MEDIUM
It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions.
CVE-2021-3491 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2021-09-14 7.2 HIGH 8.8 HIGH
The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b ("io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers") (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c ("io_uring: add IORING_OP_PROVIDE_BUFFERS") (v5.7-rc1).
CVE-2021-3490 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2021-09-14 7.2 HIGH 7.8 HIGH
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e ("bpf: Fix alu32 const subreg bound tracking on bitwise operations") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. The AND/OR issues were introduced by commit 3f50f132d840 ("bpf: Verifier, do explicit ALU32 bounds tracking") (5.7-rc1) and the XOR variant was introduced by 2921c90d4718 ("bpf:Fix a verifier failure with xor") ( 5.10-rc1).
CVE-2021-3489 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2021-09-14 7.2 HIGH 7.8 HIGH
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee ("bpf, ringbuf: Deny reserve of buffers larger than ringbuf") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") (v5.8-rc1).
CVE-2019-20421 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2021-09-14 7.8 HIGH 7.5 HIGH
In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.
CVE-2020-11937 1 Canonical 2 Ubuntu Linux, Whoopsie 2021-09-13 2.1 LOW 5.5 MEDIUM
In whoopsie, parse_report() from whoopsie.c allows a local attacker to cause a denial of service via a crafted file. The DoS is caused by resource exhaustion due to a memory leak. Fixed in 0.2.52.5ubuntu0.5, 0.2.62ubuntu0.5 and 0.2.69ubuntu0.1.
CVE-2020-15707 8 Canonical, Debian, Gnu and 5 more 15 Ubuntu Linux, Debian Linux, Grub2 and 12 more 2021-09-13 4.4 MEDIUM 6.4 MEDIUM
Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
CVE-2019-7305 3 Canonical, Debian, Extplorer 3 Ubuntu Linux, Debian Linux, Extplorer 2021-09-13 7.5 HIGH 9.8 CRITICAL
Information Exposure vulnerability in eXtplorer makes the /usr/ and /etc/extplorer/ system directories world-accessible over HTTP. Introduced in the Makefile patch file debian/patches/debian-changes-2.1.0b6+dfsg-1 or debian/patches/adds-a-makefile.patch, this can lead to data leakage, information disclosure and potentially remote code execution on the web server. This issue affects all versions of eXtplorer in Ubuntu and Debian
CVE-2013-0256 2 Canonical, Ruby-lang 3 Ubuntu Linux, Rdoc, Ruby 2021-09-09 4.3 MEDIUM N/A
darkfish.js in RDoc 2.3.0 through 3.12 and 4.x before 4.0.0.preview2.1, as used in Ruby, does not properly generate documents, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted URL.
CVE-2013-7423 4 Canonical, Gnu, Opensuse and 1 more 4 Ubuntu Linux, Glibc, Opensuse and 1 more 2021-09-01 5.0 MEDIUM N/A
The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.
CVE-2017-5715 7 Arm, Canonical, Debian and 4 more 221 Cortex-a, Ubuntu Linux, Debian Linux and 218 more 2021-08-16 1.9 LOW 5.6 MEDIUM
