QEMU: slirp: use-after-free in ip_reass() function in ip_input.c

A use-after-free flaw was found in the SLiRP networking implementation of the QEMU emulator. Specifically, this flaw occurs in the ipreass routine while reassembling incoming IP fragments whose combined size is bigger than 65k. This flaw allows an attacker to crash the QEMU process on the host,...

QEMU: Slirp: use-after-free during packet reassembly

A use-after-free issue was found in the SLiRP networking implementation of the QEMU emulator. The issue occurs in ipreass routine while reassembling incoming packets, if the first fragment is bigger than the m-mdat buffer. A user or process could use this flaw to crash the QEMU process on the hos...
