qemu-kvm: pcie: improper validation of NumVFs leads to buffer overflow
A flaw was found in the SR/IOV emulation support of QEMU. The registervfs function in hw/pci/pciesriov.c mishandled the situation where a guest writes NumVFs greater than TotalVFs, leading to a buffer overflow in VF Virtual Function implementations. This flaw allows a malicious guest to crash QEM...
Heap-Based Buffer Overflow
MicroPython is vulnerable to a Heap-based buffer overflow. The vulnerability is due to improper string length comparison during the VFS unmount process in the mpvfsumount function, which allows a remote attacker to trigger a heap buffer overflow read by supplying a crafted unmount path...

The Samba vfs_fruit module uses extended file attributes (EA xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd typically root.
