USN-5884-1: Linux kernel (AWS) vulnerabilities

Read Time:1 Minute, 12 Second

Kirill Tkhai discovered that the XFS file system implementation in the
Linux kernel did not calculate size correctly when pre-allocating space in
some situations. A local attacker could use this to expose sensitive
information. (CVE-2021-4155)

Lee Jones discovered that a use-after-free vulnerability existed in the
Bluetooth implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2022-20566)

Duoming Zhou discovered that a race condition existed in the SLIP driver in
the Linux kernel, leading to a null pointer dereference vulnerability. An
attacker could use this to cause a denial of service (system crash).
(CVE-2022-41858)

Tamás Koczka discovered that the Bluetooth L2CAP implementation in the
Linux kernel did not properly initialize memory in some situations. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-42895)

José Oliveira and Rodrigo Branco discovered that the prctl syscall
implementation in the Linux kernel did not properly protect against
indirect branch prediction attacks in some situations. A local attacker
could possibly use this to expose sensitive information. (CVE-2023-0045)

It was discovered that the RNDIS USB driver in the Linux kernel contained
an integer overflow vulnerability. A local attacker with physical access
could plug in a malicious USB device to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2023-23559)

Defense in depth — the Microsoft way (part 82): INVALID/BOGUS AppLocker rules disable SAFER on Windows 11 22H2

Read Time:20 Second

Posted by Stefan Kanthak on Feb 22

Hi @ll,

in Windows 11 22H2. some imbeciles from Redmond added the following
(of course WRONG and INVALID) registry entries and keys which they
dare to ship to their billion world-wide users:

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSrpGp]
“RuleCount”=dword:00000002
“LastWriteTime”=hex(b):01,00,00,00,00,00,00,00

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSrpGpDLL]

JFTR: the time stamp is 100ns past…
