There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2.

The Weave server API allows remote users to fetch files from a specific directory, but due to a lack of input validation, it is possible to traverse and leak arbitrary files remotely. In various common scenarios, this allows a low-privileged user to assume the role of the server admin.

The query functionality of WinMatrix3 Web package from Simopro Technology lacks proper validation of user input, allowing unauthenticated remote attackers to inject SQL commands to read, modify, and delete database contents.

An issue was discovered in Juju that resulted in the leak of the sensitive context ID, which allows a local unprivileged attacker to access other sensitive data or relation accessible to the local charm.

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in ProfilePress Membership Team Paid Membership Plugin, Ecommerce, Registration Form, Login Form, User Profile & Restrict Content – ProfilePress.This issue affects Paid Membership Plugin, Ecommerce, Registration Form, Login Form, User Profile & Restrict Content – ProfilePress: from n/a through 4.13.2.

The login functionality of WinMatrix3 Web package from Simopro Technology lacks proper validation of user input, allowing unauthenticated remote attackers to inject SQL commands to read, modify, and delete database contents.

In snapd versions prior to 2.62, snapd failed to properly check the destination of symbolic links when extracting a snap. The snap format is a squashfs file-system image and so can contain symbolic links and other file types. Various file entries within the snap squashfs image (such as icons and desktop files etc) are directly read by snapd when it is extracted. An attacker who could convince a user to install a malicious snap which contained symbolic links at these paths could then cause snapd to write out the contents of the symbolic link destination into a world-readable directory. This in-turn could allow an unprivileged user to gain access to privileged information.

There is a cross-site scripting vulnerability in the Secure Access administrative console of Absolute Secure Access prior to version 13.07. Attackers with system administrator permissions can interfere with another system administrator’s use of the publishing UI when the administrators are editing the same management object. The scope is unchanged, there is no loss of confidentiality. Impact to system availability is none, impact to system integrity is high.

In snapd versions prior to 2.62, when using AppArmor for enforcement of sandbox permissions, snapd failed to restrict writes to the $HOME/bin path. In Ubuntu, when this path exists, it is automatically added to the users PATH. An attacker who could convince a user to install a malicious snap which used the 'home' plug could use this vulnerability to install arbitrary scripts into the users PATH which may then be run by the user outside of the expected snap sandbox and hence allow them to escape confinement.
