Debian Linux Security Advisory 5271-1 - Several vulnerabilities were discovered in libxml2, a library providing support to read, modify and write XML and HTML files.

Investment round led by 11.2 Capital, Okta Ventures, and Mango Capital.

In s::can moni::tools in versions below 4.2 an unauthenticated attacker could get any file from the device by path traversal in the camera-file module.

Python 3.9.x and 3.10.x through 3.10.8 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract namespace sockets by default. Support for users manually specifying an abstract namespace socket was added as a bugfix in 3.7.8 and 3.8.4, but users would need to make specific uncommo...

A buffer overflow was discovered in NTFS-3G before 2022.10.3. Crafted metadata in an NTFS image can cause code execution. A local attacker can exploit this if the ntfs-3g binary is setuid root. A physically proximate attacker can exploit this if NTFS-3G software is configured to execute upon attachment of an external storage device.

The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

jhead 3.06 is vulnerable to Buffer Overflow via exif.c in function Put16u.

Debian Linux Security Advisory 5270-1 - Yuchen Zeng and Eduardo Vela discovered a buffer overflow in NTFS-3G, a read-write NTFS driver for FUSE, due to incorrect validation of some of the NTFS metadata. A local user can take advantage of this flaw for local root privilege escalation.

Red Hat Security Advisory 2022-7410-01 - Red Hat Single Sign-On 7.6 is a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications. This release of Red Hat Single Sign-On 7.6.1 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.6.0, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Issues addressed include HTTP request smuggling, code execution, cross site scripting, and denial of service vulnerabilities.
