1 CVE-2007-5730 119 Exec Code Overflow 2007-10-30 2011-10-17
6.6
 None Local Medium Single system Complete Complete Complete
Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability.
2 CVE-2007-5729 119 Exec Code Overflow 2007-10-30 2009-01-31
6.6
 None Local Medium Single system Complete Complete Complete
The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability.
3 CVE-2007-1366 2007-05-02 2008-12-20
4.9
 None Local Low Not required None None Complete
QEMU 0.8.2 allows local users to crash a virtual machine via the divisor operand to the aam instruction, as demonstrated by "aam 0x0," which triggers a divide-by-zero error.
4 CVE-2007-1322 2007-05-02 2008-12-20
4.9
 None Local Low Not required None None Complete
QEMU 0.8.2 allows local users to halt a virtual machine by executing the icebp instruction.
5 CVE-2007-1321 189 Overflow Bypass 2007-10-30 2011-10-11
6.6
 None Local Medium Single system Complete Complete Complete
Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.
6 CVE-2007-1320 119 Exec Code Overflow 2007-05-02 2010-12-21
7.2
 Admin Local Low Not required Complete Complete Complete
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
7 CVE-2006-0635 Overflow 2006-02-10 2008-09-05
4.6
 User Local Low Not required Partial Partial Partial
Tiny C Compiler (TCC) 0.9.23 (aka TinyCC) evaluates the "i>sizeof(int)" expression to false when i equals -1, which might introduce integer overflow vulnerabilities into applications that could be exploited by context-dependent attackers.
