An integer overflow was addressed with improved input validation. This issue is fixed in iOS 15.6 and iPadOS 15.6, macOS Monterey 12.5. An app may be able to execute arbitrary code with kernel privileges.

Integer Overflow in Fuchsia Kernel

The Security Team discovered an integer overflow bug that allows an attacker with code execution to issue memory cache invalidation operations on pages that they don’t own, allowing them to control kernel memory from userspace. We recommend upgrading to kernel version 4.1 or beyond.

Heap-memory write in FFMPEG

A heap out-of-bounds memory write exists in FFMPEG since version 5.1. The size calculation in `build_open_gop_key_points()` goes through all entries in the loop and adds `sc->ctts_data[i].count` to `sc->sample_offsets_count`. This can lead to an integer overflow resulting in a small allocation with `av_calloc()`. An attacker can cause remote code execution via a malicious mp4 file. We recommend upgrading past commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05

tcpdump: multiple overflow issues in protocol decoding

The BOOTP parser in tcpdump before 4.9.0 has a buffer overflow in print-bootp.c:bootp_print().

tcpdump: multiple overflow issues in protocol decoding

The IPv6 parser in tcpdump before 4.9.0 has a buffer overflow in print-ip6.c:ip6_print().

tcpdump: multiple overflow issues in protocol decoding

The ISAKMP parser in tcpdump before 4.9.0 has a buffer overflow in print-isakmp.c:ikev2_e_print().

icoutils: Check_offset overflow on 64-bit systems

Integer overflow in the wrestool program in icoutils before 0.31.1 allows remote attackers to cause a denial of service (memory corruption) via a crafted executable, which triggers a denial of service (application crash) or the possibility of execution of arbitrary code.

libplist: Memory allocation error in parse_data_node

The parse_data_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (memory allocation error) via a crafted plist file.

libplist: Integer overflow in parse_string_node

The parse_string_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (memory allocation error) via a crafted plist file.

Integer overflow in the vrend_create_shader function in vrend_renderer.c in virglrenderer before 0.6.0 allows local guest OS users to cause a denial of service (process crash) via crafted pkt_length and offlen values, which trigger an out-of-bounds access.

php: Use of uninitialized memory in unserialize()

Zend/zend_hash.c in PHP before 7.0.15 and 7.1.x before 7.1.1 mishandles certain cases that require large array allocations, which allows remote attackers to execute arbitrary code or cause a denial of service (integer overflow, uninitialized memory access, and use of arbitrary destructor function pointers) via crafted serialized data.

tcpdump: multiple overflow issues in protocol decoding

The OTV parser in tcpdump before 4.9.0 has a buffer overflow in print-otv.c:otv_print().

tcpdump: multiple overflow issues in protocol decoding

In tcpdump before 4.9.0, a bug in multiple protocol parsers (Geneve, GRE, NSH, OTV, VXLAN and VXLAN GPE) could cause a buffer overflow in print-ether.c:ether_print().

vim: Integer overflow at an unserialize_uep memory allocation site

An integer overflow at an unserialize_uep memory allocation site would occur for vim before patch 8.0.0378, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.

Integer overflow in base/PdfParser.cpp in PoDoFo 0.9.4 allows remote attackers to have unspecified impact via a crafted file.

gtk-vnc: Integer overflow when processing SetColorMapEntries

Multiple integer overflows in the (1) vnc_connection_server_message and (2) vnc_color_map_set functions in gtk-vnc before 0.7.0 allow remote servers to cause a denial of service (crash) or possibly execute arbitrary code via vectors involving SetColorMapEntries, which triggers a buffer overflow.

Qemu: usb: integer overflow in emulated_apdu_from_guest

Integer overflow in the emulated_apdu_from_guest function in usb/dev-smartcard-reader.c in Quick Emulator (Qemu), when built with the CCID Card device emulator support, allows local users to cause a denial of service (application crash) via a large Application Protocol Data Units (APDU) unit.

Qemu: virtio: integer overflow in handling virtio-crypto requests

Integer overflow in hw/virtio/virtio-crypto.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow.

vim: Integer overflow at a u_read_undo memory allocation site

An integer overflow at a u_read_undo memory allocation site would occur for vim before patch 8.0.0377, if it does not properly validate values for tree length when reading a corrupted undo file, which may lead to resultant buffer overflows.

An issue was discovered in ytnef before 1.9.1. This is related to a patch described as "5 of 9. Integer Overflow."
