VAR-200608-0056
Vulnerability from variot - Updated: 2025-04-03 22:32Buffer overflow in the Xsan Filesystem driver on Mac OS X 10.4.7 and OS X Server 10.4.7 allows local users with Xsan write access, to execute arbitrary code via unspecified vectors related to "processing a path name.". A buffer overflow vulnerability in Apple's Xsan product may allow a local attacker to run arbitrary code with root privileges or create a denial-of-service condition. Apple Xsan filesystem is prone to a buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it into an insufficiently sized buffer. Failed exploit attempts will likely crash the system, denying service to legitimate users.
Hardcore Disassembler / Reverse Engineer Wanted!
Want to work with IDA and BinDiff? Want to write PoC's and Exploits?
Your nationality is not important. We will get you a work permit, find an apartment, and offer a relocation compensation package.
