Last modified
CVE-2011-1020 is a vulnerability of currently unknown severity. The proc filesystem implementation in the Linux kernel 2.6.37 and earlier does not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allows local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls.. EPSS estimates a 0.92% chance of exploitation in the next 30 days.
