USN-6625-3: Linux kernel (Raspberry Pi) vulnerabilities

Read Time:51 Second

Marek Marczykowski-Górecki discovered that the Xen event channel
infrastructure implementation in the Linux kernel contained a race
condition. An attacker in a guest VM could possibly use this to cause a
denial of service (paravirtualized device unavailability). (CVE-2023-34324)

Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver
in the Linux kernel during device removal. A privileged attacker could use
this to cause a denial of service (system crash). (CVE-2023-35827)

It was discovered that a race condition existed in the Linux kernel when
performing operations with kernel objects, leading to an out-of-bounds
write. A local attacker could use this to cause a denial of service (system
crash) or execute arbitrary code. (CVE-2023-45863)

黄思聪 discovered that the NFC Controller Interface (NCI) implementation in
the Linux kernel did not properly handle certain memory allocation failure
conditions, leading to a null pointer dereference vulnerability. A local
attacker could use this to cause a denial of service (system crash).

Read Time:40 Second

It was discovered that LibTIFF incorrectly handled certain files. If
a user were tricked into opening a specially crafted file, an attacker
could possibly use this issue to cause the application to crash, resulting
in a denial of service. (CVE-2023-52356)

It was discovered that LibTIFF incorrectly handled certain image files
with the tiffcp utility. If a user were tricked into opening a specially
crafted image file, an attacker could possibly use this issue to cause
tiffcp to crash, resulting in a denial of service. (CVE-2023-6228)

It was discovered that LibTIFF incorrectly handled certain files. If
a user were tricked into opening a specially crafted file, an attacker
could possibly use this issue to cause the application to consume
resources, resulting in a denial of service. (CVE-2023-6277)

nxdomain-redirect is enabled. A remote attacker could possibly use this
issue to cause Bind to crash, leading to a denial of service.
(CVE-2023-5517)

It was discovered that Bind incorrectly handled certain specific recursive
query patterns. A remote attacker could possibly use this issue to cause
Bind to consume memory, leading to a denial of service. (CVE-2023-6516)
