Уязвимость компонент kernel/bpf/verifier.c ядра операционной системы Linux, позволяющая нарушителю повысить свои привилегии до уровня root

kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit.

Уязвимость реализации функций read_fru_area(), read_fru_area_section(), ipmi_spd_print_fru(), ipmi_get_session_info(), ipmi_get_channel_cipher_suites() и get_lan_param_select() утилиты для управления и настройки устройств с поддержкой IPMI ipmitool, позволяющая нарушителю вызвать отказ в обслуживании или выполнить произвольный код

Уязвимость функции read_fru_area_section (lib/ipmi_fru.c) утилиты для управления и настройки устройств с поддержкой IPMI ipmitool, связанная с выходом операции за границы буфера в памяти, позволяющая нарушителю выполнить произвольный код

It's been found that multiple functions in ipmitool before 1.8.19 neglect proper checking of the data received from a remote LAN party, which may lead to buffer overflows and potentially to remote code execution on the ipmitool side. This is especially dangerous if ipmitool is run as a privileged user. This problem is fixed in version 1.8.19.

In the ffghbn function in NASA CFITSIO 3.42, specially crafted images parsed via the library can cause a stack-based buffer overflow overwriting arbitrary data. An attacker can deliver an FIT image to trigger this vulnerability and potentially gain code execution.
