|---|---|---|---|---|---|
| CVE-2021-4034 | 7 Canonical, Oracle, Polkit Project and 4 more | 31 Ubuntu Linux, Http Server, Zfs Storage Appliance Kit and 28 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. | |||||

| CVE-2021-20233 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 7.2 HIGH | 8.2 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2021-20225 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 7.2 HIGH | 6.7 MEDIUM |
| A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-27779 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 6.9 MEDIUM | 7.5 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-27749 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 7.2 HIGH | 6.7 MEDIUM |
| A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-25647 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 7.2 HIGH | 7.6 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-25632 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2024-11-21 | 7.2 HIGH | 8.2 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-14372 | 4 Fedoraproject, Gnu, Netapp and 1 more | 9 Fedora, Grub2, Cloud Backup and 6 more | 2024-11-21 | 6.2 MEDIUM | 7.5 HIGH |
| A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability. | |||||
| CVE-2019-9948 | 6 Canonical, Debian, Fedoraproject and 3 more | 11 Ubuntu Linux, Debian Linux, Fedora and 8 more | 2024-11-21 | 6.4 MEDIUM | 9.1 CRITICAL |
| urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call. | |||||
| CVE-2019-9636 | 7 Canonical, Debian, Fedoraproject and 4 more | 16 Ubuntu Linux, Debian Linux, Fedora and 13 more | 2024-11-21 | 5.0 MEDIUM | 9.8 CRITICAL |
| Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed correctly.
