CVSS v3.1 |
| Zulip is an open-source team collaboration tool. In Zulip Server versions through 12.1, guest users can receive new message events for public channels outside their subscriptions. A guest can trigger the issue by registering an event queue with parameters that request messages from an unsubscribed public channel, or an existing event queue can remain affected after the guest's access to the channel is removed. The flaw discloses new public-channel messages to the guest. This issue is fixed in version 12.2. |
| 3proxy from 0.9.7 through 1.0.1, fixed in commit 206c923, contains an uninitialized stack memory disclosure vulnerability that allows unauthenticated attackers to leak stack bytes via the SOCKS4 reply path when the external-NAT option (-Ne) is configured. Attackers can send a client probe that fails the SOCKS version check to trigger a reply containing uninitialized bytes from the sin structure, exposing high bytes of a userspace pointer that weakens ASLR protections. |
| A Use of Externally-Controlled Format String vulnerability in the jti-dialoutd of Juniper Networks Junos OS Evolved allows an authenticated network attacker to cause persistent telemetry dial-out denial of service via a crafted analytics sensor resource submitted through gNMI listener. |
| An OS Command Injection vulnerability in the bootzd zero-touch provisioning daemon of Juniper Networks Junos OS Evolved allows an unauthenticated attacker on the management LAN to execute commands as root via crafted DHCP response. |
| A Heap-based Buffer Overflow vulnerability in the VXLAN Gateway Daemon (vgd) of Juniper Networks Junos OS allows a malicious or compromised SDN-controller to cause a complete outage of the OVSDB control plane and possibly remote code execution. |
| An SQL injection vulnerability could allow an authenticated user to read or modify data stored by Nessus. |
| An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker which sends a specific set of BGP communities to cause a Denial-of-Service (DoS) as rpd crashes when graceful-shutdown sender community is added when attempting to advertise. |
| F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Svc::Ccsds::SpacePacketDeframer dataIn_handler is vulnerable because the handler treats the minimum packet-length condition as FW_ASSERT rather than rejecting and returning the buffer. When a CCSDS telecommand frame leaves a payload of six bytes or fewer after TcDeframer removes its header and trailer, the assertion aborts or resets the flight-software process, causing denial of service. This issue is fixed in version 4.2.0. |
| F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.3.0, Svc::FileUplink handling of Fw::FilePacket::StartPacket destination paths FileUplink copies the packet-controlled destinationPath and opens it for writing without canonicalization or confinement to an upload directory. When a peer able to send file-uplink packets supplies an absolute, traversing, or otherwise attacker-selected writable destination path, files can be created or overwritten at attacker-selected writable filesystem locations, affecting integrity and potentially availability. This issue is fixed in version 4.3.0. |
| An Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in ipfd of Juniper Networks Junos OS on SRX Series allows an unauthenticated network-based attacker to execute code with root privileges via a configured Security Intelligence feed connection. |
| A Reachable Assertion vulnerability in the
l2ald
daemon of Juniper Networks Junos OS and Junos OS Evolved devices configured for MC-LAG/ICCP allows an adjacent attacker to cause a denial of service via an inconsistent ICCP peer message. |
| A flaw was found in the DPDK GSO library. When software GSO copies packet headers into a new mbuf, it does not check that the header fits in the source first segment or in the destination buffer, and a header longer than the configured GSO segment size can underflow the payload-size calculation. A remote or guest-supplied packet processed with software GSO can trigger an out-of-bounds read or write. |
| A Reachable Assertion vulnerability in the srxpfe process of Juniper Networks Junos OS on SRX Series allows an adjacent network attacker to cause a denial of service of the data plane via malformed firewall-authentication synchronization traffic on chassis-cluster fabric interfaces. |
| An Integer Underflow (Wrap or Wraparound) vulnerability in the srxpfe of Juniper Networks Junos OS and Junos OS Evolved on the SRX Series allows an adjacent unauthenticated attacker to cause a forwarding-plane denial of service via an ICMP message associated with an SVR carrier session. |
| A NULL Pointer Dereference vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a configured peer sending a BGP UPDATE to cause a denial of service when an import policy with `then source-based-forwarding next-hop next-table <X>` is configured to reference a routing table that does not exist. |
| An Improper Input Validation vulnerability in the rpd process of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause a denial of service via a malformed PIM Hello message received on an IPv6-enabled PIM interface. |
| A Use After Free vulnerability in the rpd PIM Join/Prune processing of Juniper Networks Junos OS and Junos OS Evolved platforms allows an unauthenticated adjacent attacker to crash the routing daemon via specific PIM messages when sparse mode PIM is configured. |
| adm-zip 0.6.0 contains a decompression bomb protection bypass that allows attackers to evade the maxOutputLength guard by targeting the asynchronous getDataAsync() path in methods/inflater.js. Attackers can craft ZIP entries with falsified small declared sizes and high-ratio DEFLATE payloads to exhaust memory in applications reading entries asynchronously. |
| sharp before 0.35.5 bundles a librsvg dependency affected by a memory-related vulnerability (CVE-2026-96889) that, under certain runtime-specific conditions, can lead to code execution on glibc-based Linux. An attacker can supply a crafted SVG image that, when decoded by sharp through librsvg, may result in arbitrary code execution. |

bpf: Fix UAF due to concurrent consumption of ttrace lists in alloc_bulk
Syzkaller repeatedly triggered UAF splats related to nodes in
waiting_for_gp_ttrace within the bpf memalloc:
BUG: KASAN: slab-use-after-free in llist_del_first+0x85/0x110 lib/llist.c:61

rcu_tasks_kthread+0xf3/0x120 kernel/rcu/tasks.h:651
The reason is that the UAF occurs after the RCU Tasks Trace GP expires:
when the __free_rcu() callback runs, there is no synchronization
protecting llist_del_all() against concurrent alloc_bulk() operating on
waiting_for_gp_ttrace, leading to the race condition below:
CPU0 CPU1
__free_rcu (RCU Tasks Trace callback)
alloc_bulk
llist_del_first(&c->waiting_for_gp_ttrace)
entry = smp_load_acquire(&head->first);
do {
if (entry == NULL)
return NULL;
free_all(llist_del_all(&c->waiting_for_gp_ttrace))
llist_for_each_safe(pos, t, llnode)
free_one(pos);
next = READ_ONCE(entry->next); <-- trigger UAF
} while (!try_cmpxchg(&head->first, &entry, next));
In addition, there is also a theoretical race condition on the
free_by_rcu_ttrace list. This race requires two preconditions: an
in-flight Tasks Trace GP keeping c->call_rcu_ttrace_in_progress == 1,
and concurrent cross-CPU frees repopulating c->free_by_rcu_ttrace with
new nodes. Under these conditions, the following scenario triggers UAF:
// CPU0
// irq work is still busy (on PREEMPT_RT)
alloc_bulk()
llist_del_first(&c->free_by_rcu_ttrace)
entry = smp_load_acquire(&head->first);
do {
if (entry == NULL)
return NULL;
// CPU1
bpf_mem_alloc_destroy()
WRITE_ONCE(c->draining, true)
// wait for CPU0
irq_work_sync()
// CPU2
do_call_rcu_ttrace(tgt(CPU0))
if (c->draining) {
llist_del_all(&c->free_by_rcu_ttrace)
free_all()
}
// CPU0 continue
next = READ_ONCE(entry->next); <-- trigger UAF
while (!try_cmpxchg(&head->first, &entry, next));
Fix this by introducing a raw spinlock to synchronize the concurrent
consumption on waiting_for_gp_ttrace and free_by_rcu_ttrace. |
