Title:	Debian LTS: Security Advisory for qemu (DLA-2288-1)
Summary:	The remote host is missing an update for the 'qemu'; package(s) announced via the DLA-2288-1 advisory.
Description:	Summary: The remote host is missing an update for the 'qemu' package(s) announced via the DLA-2288-1 advisory. Vulnerability Insight: The following CVE(s) were reported against src:qemu: CVE-2017-9503 QEMU (aka Quick Emulator), when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving megasas command processing. CVE-2019-12068 In QEMU 1:4.1-1 (1:2.8+dfsg-6+deb9u8), when executing script in lsi_execute_script(), the LSI scsi adapter emulator advances 's->dsp' index to read next opcode. This can lead to an infinite loop if the next opcode is empty. Move the existing loop exit after 10k iterations so that it covers no-op opcodes as well. CVE-2019-20382 QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd. CVE-2020-1983 A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service. CVE-2020-8608 In libslirp 4.1.0, as used in QEMU 4.2.0, tcp_subr.c misuses snprintf return values, leading to a buffer overflow in later code. CVE-2020-10756 An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1. CVE-2020-13361 In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation. CVE-2020-13362 In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a crafted reply_queue_head field from a guest OS user. CVE-2020-13659 address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer. CVE-2020-13754 hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation. CVE-2020-13765 rom_copy() in hw/core/loader.c in QEMU 4.1.0 does not validate the relationship between two addresses, which allows attackers to trigger an invalid memory copy operation. CVE-2020-15863 Stack-based overflow in xgmac_enet_send() in hw/net/xgmac.c. Affected Software/OS: 'qemu' package(s) on Debian Linux. Solution: For Debian 9 stretch, these problems have been fixed in version 1:2.8+dfsg-6+deb9u10. We recommend that you upgrade your qemu packages.
