| 2020-04-22 | CVE-2020-8831 | Apport creates a world writable lock file with root ownership in the world writable /var/lock/apport directory. If the apport/ directory does not exist (this is not uncommon as /var/lock is a tmpfs), it will create the directory, otherwise it will simply continue execution using the existing directory. This allows for a symlink attack if an attacker were to create a symlink at /var/lock/apport, changing apport's lock file location. This file could then be used to escalate privileges, for... | Apport, Ubuntu_linux | 5.5 | ||
| 2020-04-22 | CVE-2020-8833 | Time-of-check Time-of-use Race Condition vulnerability on crash report ownership change in Apport allows for a possible privilege escalation opportunity. If fs.protected_symlinks is disabled, this can be exploited between the os.open and os.chown calls when the Apport cron script clears out crash files of size 0. A symlink with the same name as the deleted file can then be created upon which chown will be called, changing the file owner to root. Fixed in versions 2.20.1-0ubuntu2.23,... | Apport, Ubuntu_linux | 4.7 | ||
| 2020-04-23 | CVE-2020-1760 | A flaw was found in the Ceph Object Gateway, where it supports request sent by an anonymous user in Amazon S3. This flaw could lead to potential XSS attacks due to the lack of proper neutralization of untrusted input. | Ubuntu_linux, Debian_linux, Fedora, Ceph, Ceph_storage, Openshift_container_platform | 6.1 | ||
| 2020-04-30 | CVE-2020-1752 | A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32. | Ubuntu_linux, Debian_linux, Glibc, Active_iq_unified_manager, H410c_firmware, Hci_management_node, Solidfire, Steelstore_cloud_integrated_storage | 7.0 | ||
| 2020-05-05 | CVE-2020-12656 | gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c in the rpcsec_gss_krb5 implementation in the Linux kernel through 5.6.10 lacks certain domain_release calls, leading to a memory leak. Note: This was disputed with the assertion that the issue does not grant any access not already available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount... | Ubuntu_linux, Linux_kernel, Leap | 5.5 | ||
| 2020-05-07 | CVE-2020-12689 | An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any user authenticated within a limited scope (trust/oauth/application credential) can create an EC2 credential with an escalated permission, such as obtaining admin while the user is on a limited viewer role. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges. | Ubuntu_linux, Keystone | 8.8 | ||
| 2020-05-07 | CVE-2020-12691 | An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. Any authenticated user can create an EC2 credential for themselves for a project that they have a specified role on, and then perform an update to the credential user and project, allowing them to masquerade as another user. This potentially allows a malicious user to act as the admin on a project another user has the admin role on, which can effectively grant that user global admin privileges. | Ubuntu_linux, Keystone | 8.8 | ||
| 2020-05-07 | CVE-2020-12692 | An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times. | Ubuntu_linux, Keystone | 5.4 | ||
| 2020-05-09 | CVE-2020-12771 | An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails. | Ubuntu_linux, Debian_linux, Linux_kernel, A700s_firmware, Active_iq_unified_manager, Cloud_backup, Element_software, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H610c_firmware, H610s_firmware, H615c_firmware, H700e_firmware, H700s_firmware, Hci_bootstrap_os, Hci_management_node, Solidfire, Steelstore_cloud_integrated_storage, Leap, Sd\-Wan_edge | 5.5 | ||
