A denial-of-service vulnerability exists in the asynchronous ioctl functionality of Microsoft Azure Sphere 20.05. A sequence of specially crafted ioctl calls can cause a denial of service. An attacker can write shellcode to trigger this vulnerability.

srs2.c in PostSRSd before 1.10 allows remote attackers to cause a denial of service (CPU consumption) via a long timestamp tag in an SRS address.

cPanel before 90.0.17 has multiple instances of URL parameter injection (SEC-567).

QEMU: e1000e: infinite loop scenario in case of null packet descriptor

hw/net/e1000e_core.c in QEMU 5.0.0 has an infinite loop via an RX descriptor with a NULL buffer address.

wireshark: malformed packet on wire could make GQUIC protocol dissector loop

In Wireshark 3.2.0 to 3.2.7, the GQUIC dissector could crash. This was addressed in epan/dissectors/packet-gquic.c by correcting the implementation of offset advancement.

Kernel: KVM: host stack overflow due to lazy update IOAPIC

An issue was discovered in ioapic_lazy_update_eoi in arch/x86/kvm/ioapic.c in the Linux kernel before 5.9.2. It has an infinite loop related to improper interaction between a resampler and edge triggering, aka CID-77377064c3a9.

wireshark: FBZERO dissector could enter an infinite loop

In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.

kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS

A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

QEMU: usb: hcd-ohci: infinite loop issue while processing transfer descriptors

hw/usb/hcd-ohci.c in QEMU 5.0.0 has an infinite loop when a TD list has a loop.

An issue was discovered in the http crate before 0.1.20 for Rust. An integer overflow in HeaderMap::reserve() could result in denial of service (e.g., an infinite loop).

picoquic (before 3rd of July 2020) allows attackers to cause a denial of service (infinite loop) via a crafted QUIC frame, related to the picoquic_decode_frames and picoquic_decode_stream_frame functions and epoch==3.

An issue was discovered in picoTCP and picoTCP-NG through 1.7.0. When an unsupported TCP option with zero length is provided in an incoming TCP packet, it is possible to cause a Denial-of-Service by achieving an infinite loop in the code that parses TCP options, aka tcp_parse_options() in pico_tcp.c.

An issue was discovered in GetByte function in miniupnp ngiflib version 0.4, allows local attackers to cause a denial of service (DoS) via crafted .gif file (infinite loop).

Irfanview v4.53 was discovered to contain an infinity loop via JPEG2000!ShowPlugInSaveOptions_W+0x1ecd8.

A carefully crafted or corrupt PSD file can cause an infinite loop in Apache Tika's PSDParser in versions 1.0-1.23.

Junos OS: A specific SNMP command can trigger a high CPU usage Denial of Service in the RPD daemon.

In a Point-to-Multipoint (P2MP) Label Switched Path (LSP) scenario, an uncontrolled resource consumption vulnerability in the Routing Protocol Daemon (RPD) in Juniper Networks Junos OS allows a specific SNMP request to trigger an infinite loop causing a high CPU usage Denial of Service (DoS) condition. This issue affects both SNMP over IPv4 and IPv6. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D90; 15.1 versions prior to 15.1R7-S6; 15.1X49 versions prior to 15.1X49-D200; 15.1X53 versions prior to 15.1X53-D238, 15.1X53-D592; 16.1 versions prior to 16.1R7-S5; 16.2 versions prior to 16.2R2-S11; 17.1 versions prior to 17.1R3-S1; 17.2 versions prior to 17.2R3-S2; 17.3 versions prior to 17.3R3-S7; 17.4 versions prior to 17.4R2-S4, 17.4R3; 18.1 versions prior to 18.1R3-S5; 18.2 versions prior to 18.2R3; 18.2X75 versions prior to 18.2X75-D50; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R2.

An issue was discovered in picoTCP 1.7.0. The routine for processing the next header field (and deducing whether the IPv6 extension headers are valid) doesn't check whether the header extension length field would overflow. Therefore, if it wraps around to zero, iterating through the extension headers will not increment the current data pointer. This leads to an infinite loop and Denial-of-Service in pico_ipv6_check_headers_sequence() in pico_ipv6.c.

golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs

Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs.

accountsservice .pam_environment infinite loop

An Ubuntu-specific modification to AccountsService in versions before 0.6.55-0ubuntu13.2, among other earlier versions, would perform unbounded read operations on user-controlled ~/.pam_environment files, allowing an infinite loop if /dev/zero is symlinked to this location.

Mozilla: Custom cursor can overlay user interface

When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
