Last modified

CVE-2008-4210 is a vulnerability of currently unknown severity. fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O.. EPSS estimates a 2.14% chance of exploitation in the next 30 days.
