VLAI
Title
Bochs 2.6-5 Buffer Overflow Remote Code Execution
Summary
Bochs 2.6-5 contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by supplying an oversized input string to the application. Attackers can craft a malicious payload with 1200 bytes of padding followed by a return-oriented programming chain to overwrite the instruction pointer and execute shell commands with application privileges.

Vulnerability from nvd – Published: 2007-05-30 01:00 – Updated: 2024-08-07 13:57
VLAI
Summary
Heap-based buffer overflow in the bx_ne2k_c::rx_frame function in iodev/ne2k.cc in the emulated NE2000 device in Bochs 2.3 allows local users of the guest operating system to write to arbitrary memory locations and gain privileges on the host operating system via vectors that cause TXCNT register values to exceed the device memory size, aka "RX Frame heap overflow."
Severity
No CVSS data available.

CVE-2004-2372 (GCVE-0-2004-2372)
Vulnerability from nvd – Published: 2005-08-16 04:00 – Updated: 2024-08-08 01:22
VLAI
Summary
Buffer overflow in Bochs before 2.1.1, if installed setuid, allows local users to execute arbitrary code via a long HOME environment variable, which is used if the .bochsrc, bochsrc, and bochsrc.txt cannot be found in a known path. NOTE: some external documents recommend that Bochs be installed setuid root, so this should be treated as a vulnerability.
Severity
No CVSS data available.

Title
Bochs 2.6-5 Buffer Overflow Remote Code Execution
Summary
Bochs 2.6-5 contains a stack-based buffer overflow vulnerability that allows attackers to execute arbitrary code by supplying an oversized input string to the application. Attackers can craft a malicious payload with 1200 bytes of padding followed by a return-oriented programming chain to overwrite the instruction pointer and execute shell commands with application privileges.

CVE-2007-2893 (GCVE-0-2007-2893)
Vulnerability from cvelistv5 – Published: 2007-05-30 01:00 – Updated: 2024-08-07 13:57
VLAI
Summary
Heap-based buffer overflow in the bx_ne2k_c::rx_frame function in iodev/ne2k.cc in the emulated NE2000 device in Bochs 2.3 allows local users of the guest operating system to write to arbitrary memory locations and gain privileges on the host operating system via vectors that cause TXCNT register values to exceed the device memory size, aka "RX Frame heap overflow."
Severity
No CVSS data available.

CVE-2004-2372 (GCVE-0-2004-2372)
Vulnerability from cvelistv5 – Published: 2005-08-16 04:00 – Updated: 2024-08-08 01:22
VLAI
Summary
Buffer overflow in Bochs before 2.1.1, if installed setuid, allows local users to execute arbitrary code via a long HOME environment variable, which is used if the .bochsrc, bochsrc, and bochsrc.txt cannot be found in a known path. NOTE: some external documents recommend that Bochs be installed setuid root, so this should be treated as a vulnerability.
Severity
No CVSS data available.
