CVE-2013-4538 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
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-2013-4530 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in hw/ssi/pl022.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted tx_fifo_head and rx_fifo_head values in a savevm image.
