| Heap-based buffer overflow in SQL Server allows an unauthorized attacker to execute code over a network. |
| libconfini 1.16.4 contains a heap out-of-bounds write condition involving the bundled load_ini_buffer.h utility and strip_ini_cache(). The bundled utility allocates exactly ini_length bytes, while strip_ini_cache() unconditionally writes a NUL terminator at ini_source[ini_length], requiring an additional writable byte. Applications using the bundled allocation pattern can trigger deterministic heap memory corruption when processing any non-empty INI input, resulting in denial of service. |
| libsndfile 1.2.2 contains a misaligned memory access issue in psf_binheader_readf() while parsing WAV fmt chunks. A specially crafted WAV file can cause the function to cast an unaligned destination address to unsigned int * and perform a 4-byte store. This results in undefined behavior leading to denial of service. |
| The mysqlnd wire protocol parser reads fields out of server packets before checking that the packet still holds enough bytes for them. A malicious or compromised MySQL server can send a truncated packet and make the client read past the end of the packet buffer, which is undefined behaviour and can crash the process. |
| php_openssl_matches_wildcard_name() in ext/openssl/xp_ssl.c underflows the length argument passed to memchr() when a TLS server certificate presents a wildcard name whose literal characters are together longer than the hostname being verified. A malicious server presenting such a certificate makes the PHP client read up to SIZE_MAX bytes past the end of a heap allocation. The path is reachable from any default client stream, because verify_peer_name is enabled by default. |
| The convert.base64-encode, convert.quoted-printable-encode and convert.quoted-printable-decode stream filters accept a line-break-chars option whose length is tracked separately from the string itself. The filter constructors duplicate the value with pestrdup(), which stops at the first NUL byte, while keeping the original length. When the filter later emits a line break it copies the recorded length out of the truncated allocation, reading past its end and placing adjacent heap bytes into the filter output. |
| A heap buffer overflow vulnerability in the FileMaker Server database engine block parsing routine allowed a maliciously crafted .fmp12 database file to cause memory corruption, potentially leading to arbitrary code execution. This vulnerability is addressed in FileMaker Server version 26.0.3. |
| In the Linux kernel, the following vulnerability has been resolved:
net: dsa: bcm_sf2: bound the CFP rule dump by the caller's buffer size
bcm_sf2_cfp_rule_get_all() walks the whole cfp.unique bitmap into
rule_locs[] without consulting nfc->rule_cnt, which is how many entries
the caller had room for. ETHTOOL_GRXCLSRLALL requires no CAP_NET_ADMIN
and the ioctl sizes the buffer from the rule_cnt userspace passes in, so
once an admin has installed CFP rules any user can ask for fewer slots
than there are rules and run off the end of the allocation. A rule_cnt
of 0 leaves the buffer pointer NULL and the walk dereferences it. |
| Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally. |
| Null pointer dereference in Windows Universal Disk Format File System Driver (UDFS) allows an authorized attacker to execute code locally. |
| Bridge is affected by a Heap-based Buffer Overflow vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.2.4 until 2.5.6, configuring synth.midi-channels above 16 allows the MIDI player to index _fluid_player_t::channel_isplaying outside its fixed-size heap allocation while tracking active channels. The resulting out-of-bounds reads and writes invoke undefined behavior and may compromise confidentiality, integrity, or availability. No crafted MIDI file is required because the unsafe condition is created by the channel-count configuration itself. Keeping synth.midi-channels at its default value of 16 avoids the vulnerable path. This issue is fixed in version 2.5.6. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio_console: do not free control-out buffers on remove
__send_control_msg() publishes &portdev->cpkt as the control-out
virtqueue cookie. remove_vqs() walks every virtqueue and passes leftover
cookies to free_buf(), which treats them as struct port_buffer and
reads sgpages.
If a control message is still on c_ovq when the device is unbound,
free_buf() reads past the ports_device object.
KASAN reported slab-out-of-bounds in free_buf():
free_buf
remove_vqs
virtcons_remove
unbind_store
The object was the ports_device allocated in virtcons_probe().
Drain c_ovq without freeing. The packet lives in portdev and is released
with it. |
| In the Linux kernel, the following vulnerability has been resolved:
net: usb: cx82310_eth: drop URB after 0xffff reboot sentinel to prevent partial_data heap overflow
The 0xffff length sentinel detects a router reboot and schedules
re-enabling of ethernet mode, but then falls through to the rest
of the loop body. The next check is
} else if (len > CX82310_MTU) {
which is the else of the just-matched if -- it never fires for
len == 0xffff. The MTU bound that normally caps the
incomplete-packet save path is silently bypassed.
With 0xffff > skb->len always true (rx_urb_size is 4096), the
incomplete-packet branch saves dev->partial_len = skb->len bytes
into dev->partial_data. partial_data is kmalloc(hard_mtu) =
kmalloc(CX82310_MTU + 2) = 1516 bytes, but skb->len after the
2-byte header pull can be up to 4094. A device that sends a
4096-byte URB starting with [0xff 0xff] therefore copies 4094
device-provided bytes into a buffer allocated for 1516 bytes,
exceeding its requested size by 2578 bytes.
The next URB then reads dev->partial_len (4094) back from the same
1516-byte buffer and dev->partial_rem (65535 - 4094 = 61441) from
the new URB's ~4KB skb, both well past their allocations, and
delivers the spliced result as a 64KB "frame" to the network
stack.
Bail out of rx_fixup after scheduling the re-enable work; the
remainder of a reboot-marker URB is not meaningful packet data.
This restores the invariant that partial_len < CX82310_MTU + 2 on
the save path, since every other route there has already passed
the MTU check. |

| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP's winpr/libwinpr/sspi/Kerberos/kerberos.c kerberos_DecryptMessage function fails to bound the peer-controlled GSS Wrap-token EC field before using it with RRC in IOV pointer offsets, allowing a malicious RDP peer to trigger out-of-bounds reads and in-place writes during CredSSP/NLA Kerberos decryption. This issue is fixed in version 3.30.0. |
