FreeBSD : go -- encoding/binary: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs (bc7aff8c-d806-11ea-a5aa-0800272260e5)

The Go project reports : Certain invalid inputs to ReadUvarint or ReadVarint could cause those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This could lead to processing more input than expected when the caller is reading directly from the...

CVE-2020-7460

The CVE-2020-7460 issue affects FreeBSD on 64-bit platforms where the 32-bit compat32 sendmsg path contains a TOCTOU vulnerability. A 32-bit or 64-bit process could trigger a mailcious userspace program to modify control message headers after validation, enabling kernel-level impact. Affected ran...

FreeBSD : typo3 -- multiple vulnerabilities (eab964f8-d632-11ea-9172-4c72b94353b5)

Typo3 Team reports : In case an attacker manages to generate a valid cryptographic message authentication code HMAC-SHA1 - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation.

Impact : An attacker with physical access to a USB port and the ability to bring a network interface up may be able to use a specially...

FreeBSD Kernel sendmsg System Call Time-Of-Check Time-Of-Use Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of FreeBSD Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of...

FreeBSD : FreeBSD -- sendmsg(2) privilege escalation (8db74c04-d794-11ea-88f8-901b0ef719ab)

When handling a 32-bit sendmsg2 call, the compat32 subsystem copies the control message to be transmitted if any into kernel memory, and adjusts alignment of control message headers. The code which performs this work contained a time-of-check to time-of-use TOCTOU vulnerability which allows a...
