Sun Solaris acl(2) system call denial of service
| solaris-acl-system-dos (34147) |  Medium Risk |
Description:
Sun Solaris is vulnerable to a denial of service, caused by an integer signedness error in the acl(2) system call. By sending a specially-crafted argument that leads to a large amount of memory allocation, a local attacker could exploit this vulnerability to cause a system panic.
