Sun Solaris snoop(1M) buffer overflow
| solaris-snoop1m-bo (44222) |  High Risk |
Description:
Sun Solaris is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by snoop(1M) when the -o option is not enabled. An attacker could exploit this vulnerability using specially-crafted SMB packets to execute arbitrary code with privileges of the user or cause the application to crash.
Note: When snoop(1M) is invoked by root, an attacker could execute arbitrary code with nobody privileges.
Platforms Affected:
- Sun, OpenSolaris build_snv_95 SPARC
- Sun, OpenSolaris build_snv_95 x86
- Sun, Solaris 10 SPARC
- Sun, Solaris 10 x86
- Sun, Solaris 8 x86
- Sun, Solaris 8 SPARC
- Sun, Solaris 9 SPARC
- Sun, Solaris 9 x86
