LockBit maintained its position as the top ransomware attacker and was also observed expanding into the Mac space. (Read more...) The post Ransomware review: May 2023 appeared first on Malwarebytes Labs.
Advantech EKI-1524, EKI-1522, EKI-1521 devices through 1.21 are affected by a Stack-based Buffer Overflow vulnerability, which can be triggered by authenticated users via a crafted POST request.
A buffer overflow in the component /proc/ftxxxx-debug of FiiO M6 Build Number v1.0.4 allows attackers to escalate privileges to root.
There is an integer overflow in Shannon Baseband leading to a heap buffer overflow when reassembling IPv4 fragments. According to the debug strings, this corresponding functionality is implemented in SmdtIp4Rx::ProcessFragments function and its callees.
illumos illumos-gate before 676abcb has a stack buffer overflow in /dev/net, leading to privilege escalation via a stat on a long file name in /dev/net.
In NanoMQ v0.15.0-0, Heap overflow occurs in read_byte function of mqtt_code.c.
In NanoMQ v0.15.0-0, a Heap overflow occurs in copyn_utf8_str function of mqtt_parser.c
Gentoo Linux Security Advisory 202305-20 - A buffer overflow vulnerability has been discovered in libapreq2 which could result in denial of service. Versions less than 2.17 are affected.
An issue was discovered in bgpd in FRRouting (FRR) through 8.4. By crafting a BGP OPEN message with an option of type 0xff (Extended Length from RFC 9072), attackers may cause a denial of service (assertion failure and daemon restart, or out-of-bounds read). This is possible because of inconsistent boundary checks that do not account for reading 3 bytes (instead of 2) in this 0xff case.
Insufficient length checks in the ShapeShift KeepKey hardware wallet firmware before 7.7.0 allow a global buffer overflow via crafted messages. Flaws in cf_confirmExecTx() in ethereum_contracts.c can be used to reveal arbitrary microcontroller memory on the device screen or crash the device. With physical access to a PIN-unlocked device, attackers can extract the BIP39 mnemonic secret from the hardware wallet.
