CVE-2017-2501

TITLE

plural Apple Vulnerability in the kernel component of a product that allows arbitrary code execution in privileged contexts

DESCRIPTION

An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. macOS before 10.12.5 is affected. tvOS before 10.2.1 is affected. watchOS before 3.2.2 is affected. The issue involves the "Kernel" component. A race condition allows attackers to execute arbitrary code in a privileged context via a crafted app. Apple iOS/WatchOS/tvOS/macOS are prone to multiple security vulnerabilities. Failed exploit attempts will likely cause a denial-of-service condition. iOS/MacOS kernel uaf due to bad locking in unix domain socket file descriptor externalization unp_externalize is responsible for externalizing the file descriptors carried within a unix domain socket message. That means allocating new fd table entries in the receiver and recreating a file which looks looks (to userspace) like the file the sender sent. Here's the relevant code: ``` for (i = 0; i < newfds; i++) { <----------- (a) #if CONFIG_MACF_SOCKET /* * If receive access is denied, don't pass along * and error message, just discard the descriptor. */ if (mac_file_check_receive(kauth_cred_get(), rp[i])) { proc_fdunlock(p); unp_discard(rp[i], p); fds[i] = 0; proc_fdlock(p); continue; } #endif if (fdalloc(p, 0, &f)) panic("unp_externalize:fdalloc"); fp = fileproc_alloc_init(NULL); if (fp == NULL) panic("unp_externalize: MALLOC_ZONE"); fp->f_iocount = 0; fp->f_fglob = rp[i]; if (fg_removeuipc_mark(rp[i])) fgl[i] = rp[i]; else fgl[i] = NULL; procfdtbl_releasefd(p, f, fp); fds[i] = f;...
