Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9821 vulnerabilities reference this CWE, most recent first.

Reproduction script:

mkdir -p /mnt/nfsshare mkdir -p /mnt/nfs/netns_1 mkfs.ext4 /dev/sdb mount /dev/sdb /mnt/nfsshare systemctl restart nfs-server chmod 777 /mnt/nfsshare exportfs -i -o rw,no_root_squash *:/mnt/nfsshare

ip netns add netns_1 ip link add name veth_1_peer type veth peer veth_1 ifconfig veth_1_peer 11.11.0.254 up ip link set veth_1 netns netns_1 ip netns exec netns_1 ifconfig veth_1 11.11.0.1

ip netns exec netns_1 /root/iptables -A OUTPUT -d 11.11.0.254 -p tcp \ --tcp-flags FIN FIN -j DROP

(note: In my environment, a DESTROY_CLIENTID operation is always sent immediately, breaking the nfs tcp connection.) ip netns exec netns_1 timeout -s 9 300 mount -t nfs -o proto=tcp,vers=4.1 \ 11.11.0.254:/mnt/nfsshare /mnt/nfs/netns_1

ip netns del netns_1

The reason here is that the tcp socket in netns_1 (nfs side) has been shutdown and closed (done in xs_destroy), but the FIN message (with ack) is discarded, and the nfsd side keeps sending retransmission messages. As a result, when the tcp sock in netns_1 processes the received message, it sends the message (FIN message) in the sending queue, and the tcp timer is re-established. When the network namespace is deleted, the net structure accessed by tcp's timer handler function causes problems.

To fix this problem, let's hold netns refcnt for the tcp kernel socket as done in other modules. This is an ugly hack which can easily be backported to earlier kernels. A proper fix which cleans up the interfaces will follow, but may not be so easy to backport.

Summary
Oj: Use-After-Free in Oj::Doc Iterators via Reentrant Close
Details

Summary

Oj::Doc iterators (each_value, each_child, each_leaf) are vulnerable to a heap use-after-free. When a Ruby block yielded during iteration calls doc.close or d.close, the document's heap memory is freed while the C iterator is still running. When control returns from the block, the iterator reads from the freed region, producing a use-after-free accessible from pure Ruby.

Version

  • Software: oj gem
  • Affected: all versions with ext/oj/fast.c
  • Latest tested: 3.17.1 (confirmed present)

Details

The iterators in ext/oj/fast.c follow the pattern:

// fast.c:1505 (doc_each_child)
static VALUE doc_each_child(VALUE self, ...) {
    ...
    while (cur != NULL) {
        rb_yield(...);       // ← Ruby block executes here
        cur = cur->next;     // ← cur is now freed if block called close()
    }
}

rb_yield can invoke arbitrary Ruby code, including calling close() on the Doc or any child node, which calls ruby_sized_xfree on the backing buffer. On return, the C code reads cur->next from the freed region. All three iterators are affected.

ASAN report (each_child variant):

==253632==ERROR: AddressSanitizer: heap-use-after-free on address 0x5210000bd080
READ of size 8 at 0x5210000bd080 thread T0
    #0 doc_each_child  /ext/oj/fast.c:1505
0x5210000bd080 is located 896 bytes inside of 4064-byte region [0x5210000bcd00, 0x5210000bdce0)
freed by thread T0 here:
    #0 free
    #1 ruby_sized_xfree  (libruby-3.3.so.3.3)

All three iterators trigger the same freed region (fd shadow bytes):

0x5210000bd080:[fd]fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd

Reproduce

require 'oj'
# each_child
Oj::Doc.open('[1,2]') { |doc| doc.each_child { |d| d.close } }
# each_value
Oj::Doc.open('[1,2]') { |doc| doc.each_value { |v| doc.close } }
# each_leaf
Oj::Doc.open('[1,[2]]') { |doc| doc.each_leaf { |d| d.close } }

Strategy: Attack Surface Reduction

When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

No CAPEC attack patterns related to this CWE.
