Sun Solaris ip_set_srcfilter() function code execution
| solaris-ipsetsrcfilter-code-execution (43068) |  High Risk |
Description:
Sun Solaris could allow a local attacker to execute arbitrary code on the system, caused by an integer overflow error in the ip_set_srcfilter() function. By sending a specially-crafted SIOCSIPMSFILTER IOCTL request, a local attacker could exploit this vulnerability to cause a system panic or execute arbitrary code on the system with kernel level privileges.
Platforms Affected:
- Sun, OpenSolaris build_snv_91 x86
- Sun, OpenSolaris build_snv_91 SPARC
- Sun, Solaris 10 SPARC
- Sun, Solaris 10 x86
Remedy:
Refer to Sun Alert ID: 237965 for patch, upgrade or suggested workaround information. See References.
Consequences:
Gain Privileges

- CVE-2008-2710: Integer signedness error in the ip_set_srcfilter function in the IP Multicast Filter in uts/common/inet/ip/ip_multi.c in the kernel in Sun Solaris 10 and OpenSolaris before snv_92 allows local users to execute arbitrary code in other Solaris Zones via an SIOCSIPMSFILTER IOCTL request with a large value of the imsf->imsf_numsrc field, which triggers an out-of-bounds write of kernel memory. NOTE: this was reported as an integer overflow, but the root cause involves the bypass of a signed comparison.
