Use of transfer() instead of call() to send eth

Lines of code Vulnerability details Use of transfer instead of call to send eth Impact Use of transfer might render ETH impossible to withdraw because after istanbul hardfork, there is increases in the gas cost of the SLOAD operation and therefore breaks some existing smart contracts. Those...

CVE-2022-39389

Lightning Network Daemon lnd is an implementation of a lightning bitcoin overlay network node. All lnd nodes before version v0.15.4 are vulnerable to a block parsing bug that can cause a node to enter a degraded state once encountered. In this degraded state, nodes can continue to make payments a...

The vulnerability of the Advanced Local Procedure Call (ALPC) handler in Windows operating systems allows attackers to enhance their privileges.

The vulnerability of the Advanced Local Procedure Call ALPC in Windows operating systems is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to gain increased privileges...

CVE-2022-39389 Witness Block Parsing DoS Vulnerability in lnd

Lightning Network Daemon lnd is an implementation of a lightning bitcoin overlay network node. All lnd nodes before version v0.15.4 are vulnerable to a block parsing bug that can cause a node to enter a degraded state once encountered. In this degraded state, nodes can continue to make payments a...

kernel: net: nexthop: fix null pointer dereference when IPv6 is not enabled

In the Linux kernel, the following vulnerability has been resolved: net: nexthop: fix null pointer dereference when IPv6 is not enabled When we try to add an IPv6 nexthop and IPv6 is not enabled !CONFIGIPV6 we'll hit a NULL pointer dereference1 in the error path of nhcreateipv6 due to calling...

kernel: powerpc/rtas: Keep MSR[RI] set when calling RTAS

In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Keep MSRRI set when calling RTAS RTAS runs in real mode MSRDR and MSRIR unset and in 32-bit big endian mode MSRSF,LE unset. The change in MSR is done in enterrtas in a relatively complex way, since the MSR value cou...

hw: cpu: Intel: Post-barrier Return Stack Buffer Predictions

A flaw was found in hw. In certain processors with Intel's Enhanced Indirect Branch Restricted Speculation eIBRS capabilities, soon after VM exit or IBPB command event, the linear address following the most recent near CALL instruction prior to a VM exit may be used as the Return Stack Buffer RSB...

RLSA-2022:8400 Moderate: libtirpc security update

The libtirpc packages contain SunLib's implementation of transport-independent remote procedure call TI-RPC documentation, which includes a library required by programs in the nfs-utils and rpcbind packages. Security Fixes: libtirpc: DoS vulnerability with lots of connections CVE-2021-46828 For...

The vulnerability of the Advanced Local Procedure Call (ALPC) handler in Windows operating systems allows attackers to enhance their privileges.

The vulnerability of the Advanced Local Procedure Call ALPC in Windows operating systems is related to deficiencies in access control. Exploiting this vulnerability can allow attackers to enhance their privileges...

CVE-2022-0324

There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp...

There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp...

On _returnDust, call opcode's return value not checked

Lines of code Vulnerability details Impact The call opcode's return value not checked, which could leads to the originator lose funds. Proof of Concept The caller of Exchange.sol::execute or Exchange.sol::bulkExecute could be a contract who may not implement the fallback or receive function, when...

Exchange's _returnDust() does not validate return value of call() to send excess ETH to sender.

Lines of code Vulnerability details Impact When a caller to Exchange's execute or bulkExecute includes more ETH than is required to complete the transactions, returnDust is intended to return this excess back to the caller. However, returnDust does not validate that the call it performs to return...

A malicious user can steal all the excess balance on the pool by calling the execute function with higher amount than the selling amount

Lines of code Vulnerability details Impact When an order is matched, the Buyer has the option to pay in either ETH, WETH or via the Pool contract. The Exchange smart contract implements a function returnDust which returns the extra ETH to the user, if she overpays. The function is implemented in...

Upgraded Q -> M from #323 [1668467355303]

Judge has assessed an item in Issue 323 as M risk. The relevant finding follows: L00: beforeTokenTransfer function called with wrong params in LBToken Line 237 seems to be a copy pasta mistake from line 209 in LBToken.sol. On line 237 when burning tokens, to should be zero, and amount of from's...

Tx should revert when the call in _returnDust failed

Lines of code Vulnerability details Impact User may lose remaining ETH of the transaction Proof of Concept As the returned status of the call in returnDust is ignored, the tx will success even if the call failed, which means the caller does not get his ETH back. Tools Used n/a Recommended...

_returnETHIfAny() can silently fail, leading to an originator not getting the expected refund

Lines of code Vulnerability details The execute function refunds the unused ETH back to the originator through returnETHIfAny. This internal function uses a low-level call to transfer the ETH. The issue is that the return value of the call is not checked. As per the Solidity documentation...
