Package : qemu
Version : 1:2.1+dfsg-12+deb8u13
CVE ID : CVE-2020-7039
Debian Bug : 949085
tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanag
es
memory, as demonstrated by IRC DCC commands in EMU_IRC.
This can cause a heap-based buffer overflow or other out-of-bounds acces
s
which can lead to a DoS or potential execute arbitrary code.
For Debian 8 "Jessie", this problem has been fixed in version
1:2.1+dfsg-12+deb8u13.
We recommend that you upgrade your qemu packages.
