CVE-2017-1000365
Last modified
CVE-2017-1000365 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. This affects Linux Kernel versions 4.11.5 and earlier. EPSS estimates a 0.90% chance of exploitation in the next 30 days.
