.NET and Visual Studio Elevation of Privilege Vulnerability

kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.

A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity.

Multiple path traversal vulnerabilities exist in smbserver.py in Impacket through 0.9.22. An attacker that connects to a running smbserver instance can list and write to arbitrary files via ../ directory traversal. This could potentially be abused to achieve arbitrary code execution by replacing /etc/shadow or an SSH authorized key.

A Incorrect Default Permissions vulnerability in the packaging of cups of SUSE Linux Enterprise Server 11-SP4-LTSS, SUSE Manager Server 4.0, SUSE OpenStack Cloud Crowbar 9; openSUSE Leap 15.2, Factory allows local attackers with control of the lp users to create files as root with 0644 permissions without the ability to set the content. This issue affects: SUSE Linux Enterprise Server 11-SP4-LTSS cups versions prior to 1.3.9. SUSE Manager Server 4.0 cups versions prior to 2.2.7. SUSE OpenStack Cloud Crowbar 9 cups versions prior to 1.7.5. openSUSE Leap 15.2 cups versions prior to 2.2.7. openSUSE Factory cups version 2.3.3op2-2.1 and prior versions.
