Title: SLocate Path Malloc Integer Signing Heap Overflow Vulnerability
Severity: HIGH
Description:
slocate is the Secure Locate program. It is available for various UNIX operating systems, and is maintained by public domain.
A problem with slocate may make it possible for a local user to gain unauthorized privileges.
It has been reported that slocate is vulnerable to a signed integer overflow issue when handling data in the environment variable SLOCATE_PATH. Because of this problem, it may be possible for a local attacker to cause a heap corruption issue, potentially executing code.
The problem is in the handling of large amounts of data in the SLOCATE_PATH variable. By placing a specially crafted string in the environment variable, it could be possible for an attacker to cause the wrapping of a signed bit in an integer value, resulting in an insufficient amount of malloc'd memory. This could potentially be exploited by the attacker to execute code with the privileges of the slocate program.
