postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

kernel: crypto: caam - fix overflow on long hmac keys

A flaw was found in the Linux kernel's caam cryptographic accelerator driver. When processing a Hash-based Message Authentication Code HMAC key that exceeds the block size, the driver incorrectly handles memory allocation and copying. This can lead to an overflow, where the system attempts to rea...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the upload function. An attacker can cause the server to become unresponsive for all users by sending a specially crafted multipart form-data request with an excessively long...

dotnet: .NET Framework: Remote Denial of Service due to uncontrolled resource allocation

A flaw was found in .NET Framework. An unauthorized attacker can exploit this vulnerability remotely by causing the system to allocate resources without proper limits or throttling. This uncontrolled resource allocation can lead to a Denial of Service DoS, making the affected system unresponsive ...

dotnet: .NET: Denial of Service vulnerability due to uncontrolled resource allocation

A flaw was found in .NET where uncontrolled resource allocation can be exploited by an unauthorized attacker over a network. This vulnerability allows the attacker to exhaust available resources, leading to a Denial of Service DoS condition. The lack of limits or throttling mechanisms enables an...
