| CVE-2020-15861 | 3 Canonical, Net-snmp, Netapp | 5 Ubuntu Linux, Net-snmp, Cloud Backup and 2 more | 2024-11-21 | 7.8 High |
| Net-SNMP through 5.7.3 allows Escalation of Privileges because of UNIX symbolic link (symlink) following. | ||||
| CVE-2020-15811 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. This allows an attacker to hide a second request inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any downstream caches. | ||||
| CVE-2020-15810 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a conflicting length to be used from another Content-Length header) but relayed upstream. | ||||
| CVE-2020-15780 | 4 Canonical, Linux, Opensuse and 1 more | 6 Ubuntu Linux, Linux Kernel, Leap and 3 more | 2024-11-21 | 6.7 Medium |
| An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30. | ||||
| CVE-2020-15710 | 2 Canonical, Pulseaudio Project | 2 Ubuntu Linux, Pulseaudio | 2024-11-21 | 5.3 Medium |
| Potential double free in Bluez 5 module of PulseAudio could allow a local attacker to leak memory or crash the program. The modargs variable may be freed twice in the fail condition in src/modules/bluetooth/module-bluez5-device.c and src/modules/bluetooth/module-bluez5-device.c. Fixed in 1:8.0-0ubuntu3.14. | ||||
| CVE-2020-15708 | 1 Canonical | 1 Ubuntu Linux | 2024-11-21 | 9.3 Critical |
| Ubuntu's packaging of libvirt in 20.04 LTS created a control socket with world read and write permissions. An attacker could use this to overwrite arbitrary files or execute arbitrary code. | ||||
| CVE-2020-15707 | 8 Canonical, Debian, Gnu and 5 more | 19 Ubuntu Linux, Debian Linux, Grub2 and 16 more | 2024-11-21 | 5.7 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-2020-15706 | 7 Canonical, Debian, Gnu and 4 more | 18 Ubuntu Linux, Debian Linux, Grub2 and 15 more | 2024-11-21 | 6.4 Medium |
| GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions. | ||||
| CVE-2020-15705 | 7 Canonical, Debian, Gnu and 4 more | 18 Ubuntu Linux, Debian Linux, Grub2 and 15 more | 2024-11-21 | 6.4 Medium |
| GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions. | ||||
| CVE-2020-15704 | 1 Canonical | 2 Ppp, Ubuntu Linux | 2024-11-21 | 5.5 Medium |
| The modprobe child process in the ./debian/patches/load_ppp_generic_if_needed patch file incorrectly handled module loading. A local non-root attacker could exploit the MODPROBE_OPTIONS environment variable to read arbitrary root files. Fixed in 2.4.5-5ubuntu1.4, 2.4.5-5.1ubuntu2.3+esm2, 2.4.7-1+2ubuntu1.16.04.3, 2.4.7-2+2ubuntu1.3, 2.4.7-2+4.1ubuntu5.1, 2.4.7-2+4.1ubuntu6. Was ZDI-CAN-11504. | ||||
| CVE-2020-15702 | 1 Canonical | 2 Apport, Ubuntu Linux | 2024-11-21 | 7 High |
| TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate privileges. Fixed in 2.20.1-0ubuntu2.24, 2.20.9 versions prior to 2.20.9-0ubuntu7.16 and 2.20.11 versions prior to 2.20.11-0ubuntu27.6. Was ZDI-CAN-11234. | ||||
| CVE-2020-15701 | 1 Canonical | 2 Apport, Ubuntu Linux | 2024-11-21 | 5.5 Medium |
| An unhandled exception in check_ignored() in apport/report.py can be exploited by a local attacker to cause a denial of service. If the mtime attribute is a string value in apport-ignore.xml, it will trigger an unhandled exception, resulting in a crash. Fixed in 2.20.1-0ubuntu2.24, 2.20.9-0ubuntu7.16, 2.20.11-0ubuntu27.6. | ||||
| CVE-2020-15659 | 4 Canonical, Mozilla, Opensuse and 1 more | 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more | 2024-11-21 | 8.8 High |
