According to the versions of the qemu-kvm packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
Multiple buffer overflows in the ssd0323_load function in hw/display/ssd0323.c in QEMU before 1.7.2 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via crafted (1) cmd_len, (2) row, or (3) col values (4) row_start and row_end values or (5) col_star and col_end values in a savevm image.(CVE-2013-4538)
The ssi_sd_transfer function in hw/sd/ssi-sd.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary code via a crafted arglen value in a savevm image.(CVE-2013-4537)
Buffer overflow in hw/intc/openpic.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors related to IRQDest elements.(CVE-2013-4534)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
