- CVE-2013-4538: Multiple buffer overflows in the ssd0323_load function in hw/display/ssd0323.c allowed 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 (bsc#864769).
- CVE-2013-4539: Multiple buffer overflows in the tsc210x_load function in hw/input/tsc210x.c might have allowed remote attackers to execute arbitrary code via a crafted (1) precision, (2) nextprecision, (3) function, or (4) nextfunction value in a savevm image (bsc#864805).
