CVE-2014-8611

Status: ModifiedMedium (6.9)—

The __sflush function in fflush.c in stdio in libc in FreeBSD 10.1 and the kernel in Apple iOS before 9 mishandles failures of the write system call, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) via a crafted application.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
