glib: integer overflow in g_byte_array_new_take function when called with a buffer of 4GB or more on a 64-bit platform

An issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If gbytearraynewtake was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 232, causing unintended length truncation...

kernel: userspace applications can misuse the KVM API to cause a write of 16 bytes at an offset up to 32 GB from vcpu->run

A flaw was found in the Linux kernel. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability...

python-cryptography: Large inputs for symmetric encryption can trigger integer overflow leading to buffer overflow

A buffer-overflow flaw was found in the python-cryptography package. In certain sequences of update calls when symmetrically encrypting very large payloads 2GB could result in an integer overflow, leading to buffer overflows. Note: This fix is a workaround for the OpenSSL CVE-2021-23840 flaw...

CVE-2020-15117

In Synergy before version 1.12.0, a Synergy server can be crashed by receiving a kMsgHelloBack packet with a client name length set to 0xffffffff 4294967295 if the servers memory is less than 4 GB. It was verified that this issue does not cause a crash through the exception handler if the availab...

UBUNTU-CVE-2020-11042

In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in updatereadiconinfo. It allows reading a attacker-defined amount of client memory 32bit unsigned - 4GB to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has...
