Sun Solaris sendfilev() system call denial of service
| sun-solaris-sendfilev-dos (44396) |  Low Risk |
Description:
Sun Solaris is vulnerable to a denial of service, caused by an error in the sendfilev() system call. A local attacker could exploit this vulnerability using a specially-crafted Web page running on certain versions of Apache or a specially-crafted program that calls sendfile() directly or via the sendfilev(3EXT) routine to cause a system panic.
Platforms Affected:
- Sun, OpenSolaris build_snv_95 x86
- Sun, OpenSolaris build_snv_95 SPARC
- Sun, Solaris 10 SPARC
- Sun, Solaris 10 x86
Remedy:
Refer to Sun Alert ID: 239186 for patch, upgrade or suggested workaround information. See References.
Consequences:
