Detailsinfo

A vulnerability was found in Sun Solaris 8.0/9.0/10.0 (Operating System). It has been rated as critical. Affected by this issue is the function doprf of the file ld.so. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in ld.so.1 in Sun Solaris 8, 9, and 10 allows local users to execute arbitrary code via large precision padding values in a format string specifier in the format parameter of the doprf function. NOTE: this issue normally does not cross privilege boundaries, except in cases of external introduction of malicious message files, or if it is leveraged with other vulnerabilities such as CVE-2006-6494.

The bug was discovered 12/12/2006. The weakness was shared 12/13/2006 by Sean Larsson with iDEFENSE (Website). The advisory is shared for download at labs.idefense.com.
