CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
af_unix: Call kfree_skb() for dead unix_(sk)->oob_skb in GC.
syzbot reported a warning [0] in __unix_gc() with a repro, which
creates a socketpair and sends one socket's fd to itself using the
peer.
socketpair(AF_UNIX, SOCK_STREAM, 0, [3, 4]) = 0
sendmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\360", iov_len=1}],
msg_iovlen=1, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET,
cmsg_type=SCM_RIGHTS, cmsg_data=[3]}],
msg_controllen=24, msg_flags=0}, MSG_OOB|MSG_PROBE|MSG_DONTWAIT|MSG_ZEROCOPY) = 1
This forms a self-cyclic reference that GC should finally untangle
but does not due to lack of MSG_OOB handling, resulting in memory
leak.
Recently, commit 11498715f266 ("af_unix: Remove io_uring code for
GC.") removed io_uring's dead code in GC and revealed the problem.
The code was executed at the final stage of GC and unconditionally
moved all GC candidates from gc_candidates to gc_inflight_list.
That papered over the reported problem by always making the following
WARN_ON_ONCE(!list_empty(&gc_candidates)) false.
The problem has been there since commit 2aab4b969002 ("af_unix: fix
struct pid leaks in OOB support") added full scm support for MSG_OOB
while fixing another bug.
To fix this problem, we must call kfree_skb() for unix_sk(sk)->oob_skb
if the socket still exists in gc_candidates after purging collected skb.
Then, we need to set NULL to oob_skb before calling kfree_skb() because
it calls last fput() and triggers unix_release_sock(), where we call
duplicate kfree_skb(u->oob_skb) if not NULL.
Note that the leaked socket remained being linked to a global list, so
kmemleak also could not detect it. We need to check /proc/net/protocol
to notice the unfreed socket.

In commit 24803f38a5c0 ("igmp: do not remove igmp souce list info when set
link down"), the ip_mc_clear_src() in ip_mc_destroy_dev() was removed,
because it was also called in igmpv3_clear_delrec().
Rough callgraph:
inetdev_destroy
-> ip_mc_destroy_dev
-> igmpv3_clear_delrec
-> ip_mc_clear_src
-> RCU_INIT_POINTER(dev->ip_ptr, NULL)
However, ip_mc_clear_src() called in igmpv3_clear_delrec() doesn't
release in_dev->mc_list->sources. And RCU_INIT_POINTER() assigns the
NULL to dev->ip_ptr. As a result, in_dev cannot be obtained through
inetdev_by_index() and then in_dev->mc_list->sources cannot be released
by ip_mc_del1_src() in the sock_close. Rough call sequence goes like:
sock_close
-> __sock_release
-> inet_release
-> ip_mc_drop_socket
-> inetdev_by_index
-> ip_mc_leave_src
-> ip_mc_del_src
-> ip_mc_del1_src
So we still need to call ip_mc_clear_src() in ip_mc_destroy_dev() to free
in_dev->mc_list->sources. |
| Electron Packager bundles Electron-based application source code with a renamed Electron executable and supporting files into folders ready for distribution. A random segment of ~1-10kb of Node.js heap memory allocated either side of a known buffer will be leaked into the final executable. This memory _could_ contain sensitive information such as environment variables, secrets files, etc. This issue is patched in 18.3.1.

| nGrinder before 3.5.9 allows to set delay without limitation, which could be the cause of Denial of Service by remote attacker. |
| A potential DOS vulnerability was discovered in GitLab CE/EE affecting all versions from 10.8 before 15.1.6, all versions starting from 15.2 before 15.2.4, all versions starting from 15.3 before 15.3.2. Improper data handling on branch creation could have been used to trigger high CPU usage. |
| Apache IoTDB version 0.12.2 to 0.12.6, 0.13.0 to 0.13.2 are vulnerable to a Denial of Service attack when accepting untrusted patterns for REGEXP queries with Java 8. Users should upgrade to 0.13.3 which addresses this issue or use a later version of Java to avoid it. |
| The issue was addressed with improved memory handling. This issue is fixed in iOS 15.7.1 and iPadOS 15.7.1, iOS 16.1 and iPadOS 16. Joining a malicious Wi-Fi network may result in a denial-of-service of the Settings app. |
| A logic issue in the handling of concurrent media was addressed with improved state handling. This issue is fixed in macOS Monterey 12.4, iOS 15.5 and iPadOS 15.5. Video self-preview in a webRTC call may be interrupted if the user answers a phone call. |
| timg v1.4.4 was discovered to contain a memory leak via the function timg::QueryBackgroundColor() at /timg/src/term-query.cc. |
| strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data. |
| A Malformed h2 frame can cause 'std::out_of_range' exception when parsing priority meta data. This behavior can lead to denial-of-service. This affects all supported versions of HHVM (3.25.2, 3.24.6, and 3.21.10 and below) when using the proxygen server to handle HTTP2 requests. |
| A potential denial-of-service issue in the Proxygen handling of invalid HTTP2 settings which can cause the server to spend disproportionate resources. This affects all supported versions of HHVM (3.24.3 and 3.21.7 and below) when using the proxygen server to handle HTTP2 requests. |
| JasPer 2.0.14 has a memory leak in base/jas_malloc.c in libjasper.a when "--output-format jp2" is used. |
| An issue in the Proxygen handling of HTTP2 parsing of headers/trailers can lead to a denial-of-service attack. This affects Proxygen prior to v2018.12.31.00. |
| A potential denial-of-service issue in the Proxygen handling of invalid HTTP2 priority settings (specifically a circular dependency). This affects Proxygen prior to v2018.12.31.00. |
| The Mojolicious module before 9.11 for Perl has a bug in format detection that can potentially be exploited for denial of service. |
| An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. The SMI handler for the FwBlockServiceSmm driver uses an untrusted pointer as the location to copy data to an attacker-specified buffer, leading to information disclosure. |
