CVSS v3.1 |
| IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.9 could allow a Reader-role attacker to obtain version information that causes an uncaught exception. |
| Driftregion iso14229 before 0.10.1 contains an integer wraparound in Handle_0x38_RequestFileTransfer that lets unauthenticated attackers bypass the file path length check. Attackers can send a short RequestFileTransfer (SID 0x38) request with filePathAndNameLength 0xFFFC-0xFFFF, causing callbacks to read past the receive buffer, crashing targets or disclosing memory. |
| An issue in mp4v2 2.0.0 allows an attacker to execute arbitrary code via the MP4RtpAtom::ReadHntiType() in src/atom_rtp.cpp. A specially crafted MP4 file can cause an undersized rtp atom to produce a near-2^64 allocation size through an unchecked offset subtraction |
| CvFWD contained an integer overflow affecting service availability. Software customers upgrade to resolved maintenance release. Update all Commvault installations, including CommServe, Webserver, Command Center, MediaAgents, Clients and HyperScale |
| Integer overflow in the message buffer growth logic (mbuf_make_room) in PgBouncer 1.21.0 through 1.26.0 allows a remote attacker to cause a denial of service when max_packet_size is configured above 2147483648. A packet header declaring a length above 2^31 makes the buffer size computation overflow, leaving the growth loop unable to terminate. Because PgBouncer serves all clients from a single process, this saturates a CPU core and stalls every pooled connection until the process is restarted. Since 1.23.0 the overflow is reachable before authentication with a five-byte packet header. |
| Heap-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code over a network. |
| Integer overflow or wraparound in Windows Virtualization-Based Security (VBS) Enclave allows an authorized attacker to elevate privileges locally. |
| Integer overflow or wraparound in Windows Kernel-Mode Drivers allows an authorized attacker to elevate privileges locally. |
| RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. Prior to 2026.07, nanocoap accepts oversized CoAP Block2 option values without enforcing the 20-bit maximum block number, allowing block offset multiplication to overflow on 32-bit targets. The affected master baseline is commit aeeae69e; the verified fix is later on master and remains unreleased. The oversized value passes from coap_get_blockopt() to coap_block_slicer_init(). A remote CoAP client can send a malformed Block2 option that produces an invalid slice range and can cause out-of-bounds memory access, denial of service, or memory corruption. This vulnerability is fixed in 2026.07. |
| An Integer Overflow or Wraparound vulnerability in the routing daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an authenticated BGP peer to cause a denial of service via BGP route updates when extended-nexthop-tunnel is enabled. |
| An Integer Overflow or Wraparound vulnerability in the l2ald process of Juniper Networks Junos OS and Junos OS Evolved allows a configured EVPN BGP peer to cause a denial of service via EVPN Type-2 MAC/IP routes. |
| An Integer Overflow or Wraparound vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause a denial of service via specific OSPFv2 packets sent on an OSPF-enabled interface. |
| Integer overflow or wraparound in .NET Framework allows an unauthorized attacker to elevate privileges over a network. |
| jq is a command-line JSON processor. An integer overflow vulnerability exists through version 1.8.1 within the jvp_string_append() and jvp_string_copy_replace_bad functions, where concatenating strings with a combined length exceeding 2^31 bytes causes a 32-bit unsigned integer overflow in the buffer allocation size calculation, resulting in a drastically undersized heap buffer. Subsequent memory copy operations then write the full string data into this undersized buffer, causing a heap buffer overflow classified as CWE-190 (Integer Overflow) leading to CWE-122 (Heap-based Buffer Overflow). Any system evaluating untrusted jq queries is affected, as an attacker can crash the process or potentially achieve further exploitation through heap corruption by crafting queries that produce extremely large strings. The root cause is the absence of string size bounds checking, unlike arrays and objects which already have size limits. The issue has been addressed in commit e47e56d226519635768e6aab2f38f0ab037c09e5. |
| An Integer Overflow or Wraparound vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to cause a denial of service via specially crafted EVPN route updates from an accepted EVPN BGP peer. |
| An Integer Overflow or Wraparound vulnerability in the rpd process of Juniper Networks Junos OS and Junos OS Evolved allows a remote attacker with an established EVPN BGP peering relationship to cause a denial of service via EVPN BGP route processing. The issue affects EVPN-enabled routing instances and can disrupt control-plane adjacencies. |
| A flaw was found in GIMP. An attacker can cause a Denial of Service (DoS) or potentially disclose sensitive memory contents by convincing a user to open or preview a specially crafted Bohemia Interactive (PAA) texture file. Due to an integer overflow when calculating image dimensions during file decompression, the application allocates an undersized memory buffer. Subsequent processing reads memory past the buffer boundary, terminating the plug-in process unexpectedly. |
| A flaw was found in GIMP. An integer overflow occurs in the file-pvr plug-in when calculating memory buffer sizes for image dimensions. By tricking a user into opening or previewing a specially crafted PowerVR (.pvr) file, an attacker can trigger a heap-based buffer overflow, potentially leading to arbitrary code execution or a Denial of Service (DoS) via an application crash. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: reject out-of-range useconds in NFSv2 SETATTR/CREATE
The NFSv2 sattr decoder converts the wire useconds to nanoseconds in
svcxdr_decode_sattr():
iap->ia_atime.tv_nsec = tmp2 * NSEC_PER_USEC;
tmp2 is a u32 and NSEC_PER_USEC is 1000, so the product is computed in
unsigned long. On ILP32 that is 32 bits, and an out-of-range useconds
value such as 4294968 wraps to tv_nsec == 704. The corruption therefore
happens during decode, before any proc function can inspect the value,
and a later range check on tv_nsec would see an in-range result and
accept it. Rejecting in the decoder yields an RPC GARBAGE_ARGS reply.
NFSv2 defines no NFSERR_INVAL, so there is no NFS-level status to return
for a malformed time argument, and the check cannot move to the proc
function the way the v3/v4 nsec range checks do.
Guard the raw useconds before the multiplication and reject values
greater than 1000000. useconds == 1000000 is kept: it is the Sun
convention for "set to the current server time", and the in-tree Linux
NFSv2 client emits it in both the atime and the mtime field for a plain
touch / utimes(file, NULL) (see encode_sattr() and
xdr_encode_current_server_time() in fs/nfs/nfs2xdr.c). Rejecting 1000000
would turn that common operation into a hard decode failure for both
SETATTR and CREATE. 1000000 * NSEC_PER_USEC is 10^9, which does not wrap
on ILP32, so the Sun convention value passes through safely. Only
genuinely out-of-range values (> 1000000) are rejected. The atime and
mtime guards are therefore symmetric.
The decoder only applied the Sun convention in the mtime block, which
clears ATTR_ATIME_SET|ATTR_MTIME_SET when mtime useconds == 1000000. If a
client puts 1000000 in the atime field but not in the mtime field, the
atime block stored an out-of-range tv_nsec (10^9) and left ATTR_ATIME_SET
set, so the bogus value reached the filesystem. Apply the convention in
the atime block as well, clearing ATTR_ATIME_SET so the server uses its
current time and ignores the value. Only ATTR_ATIME_SET is cleared there.
The mtime block keeps its existing behavior, where 1000000 means "set
both atime and mtime to now".

| In the Linux kernel, the following vulnerability has been resolved:
md: do overflow check for sb->bblog_shift in super_1_load()
In super_1_load(), sb->bblog_shift is an __u8 type value loaded from on-
disk superblock. It is used for badblocks API badblocks_set() by the
following sequence,
1930 rdev->badblocks.shift = sb->bblog_shift;
1931 for (i = 0 ; i < (sectors << (9-3)) ; i++, bbp++) {
1932 u64 bb = le64_to_cpu(*bbp);
1933 int count = bb & (0x3ff);
1934 u64 sector = bb >> 10;
1935 sector <<= sb->bblog_shift;
1936 count <<= sb->bblog_shift;
1937 if (bb + 1 == 0)
1938 break;
1939 if (!badblocks_set(&rdev->badblocks, sector, count, 1))
1940 return -EINVAL;
1941 }
bb->bblog_shit is in range of 0-255, variable sector is 64bit width, for
an invalid bb->bblog_shit, it is possible to make sector be overflowed
by the following calculation,
1935 sector <<= sb->bblog_shift;
Then in turn when call badblocks_set() at line 1939 with the invalid
rdev->badblocks.shift set at line 1930, may result an overflow inside
_badblocks_clear() in block/badblocks.c.
Although there are many places to call badblocks APIs, the non-zero
shift value is only used in super_1_load(), other places always use 0 as
the shift value. Therefore it is unnecessary to do a general shift value
overflow check inside badblock API, and just check here as the caller.
This may avoid unnecessary check, make the badblocks API code more simple
and elegant. |
