Linux Kernel - VMA Use-After-Free via Buggy vmacache_flush_all() Fastpath Local Privilege Escalation

Linux Kernel - VMA Use-After-Free via Buggy vmacacheflushall Fastpath Local Privilege Escalation Since commit 615d6e8756c8 "mm: per-thread vma caching", first in 3.15, Linux has per-task VMA caches that contain up to four VMA pointers for fast lookup. VMA caches are invalidated by bumping the...

CVE-2018-17182

A security flaw was discovered in the Linux kernel. The vmacacheflushall function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free and possibly gain privileges via certain thread creation, map, unmap, invalidation, and dereference operations...

Block Overflow

github.com/ethereum/go-ethereum is vulnerable to block overflow. The library does not ensure that the end chain comes after the start chain in debug mode, causing an overwrite when processing a malformed block that can overwrite the next block in the sequence...

Schneider Electric Modicon M221 Authentication Sequence Replay Vulnerability

The Modicon M221 is a logic controller from Schneider Electric. The Schneider Electric Modicon M221 suffers from an authentication sequence replay vulnerability that can be exploited by an attacker to replay the authentication sequence, which can be used to connect to the Modicon M221 and upload...

CVE-2018-15810

Visiology Flipbox Software Suite before 2.7.0 allows directory traversal via %5c%2e%2e%2f because it does not sanitize filename parameters...

Kernel: speculative bounds check bypass store

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an...

kernel: race condition in snd_seq_write() may lead to UAF or OOB-access

ALSA sequencer core initializes the event pool on demand by invoking sndseqpoolinit when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access...

UBUNTU-CVE-2017-3224

Open Shortest Path First OSPF protocol implementations may improperly determine Link State Advertisement LSA recency for LSAs with MaxSequenceNumber. According to RFC 2328 section 13.1, for two instances of the same LSA, recency is determined by first comparing sequence numbers, then checksums, a...

UBUNTU-CVE-2017-3226

Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption i.e., setting the configuration parameter CONFIGENVAES=y read environment variables from disk as the encrypte...
