CVSS v3.1 |
| ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.7.1, the isInSubnet and isHostInSubnet methods in src/common.ts compare masked binary strings without validating that both operands use the same IP family. A cross-family containment check whose leading address bits match makes the masked strings compare equal even though IPv4 and IPv6 do not share an address space. An allowlist or denylist decision can therefore classify an address outside the intended range as contained. This issue is fixed in version 10.7.1. |
| DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in sql_type_cast_svpv.
When casting to SQL_NUMERIC, sql_type_cast_svpv passes the string pointer and length of the SV to grok_number without stringifying it first. An integer (IV) or floating-point (NV) value has no valid string pointer, so grok_number reads from an invalid address, triggering a segmentation fault.
This is reachable in Perl using the sql_type_cast function:
my $num = 42;
DBI::sql_type_cast( $num, DBI::SQL_NUMERIC, 0 ); |
| DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName.
fetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first. When FetchHashKeyName has been set to an integer (IV) or floating-point (NV) value, that pointer is invalid, so reading the key name triggers a segmentation fault.
This can be triggered with the following code:
my $dbh = DBI->connect( "dbi:ExampleP:", "", "",
{ RaiseError => 0, PrintError => 0 } );
$dbh->{FetchHashKeyName} = 42;
my $sth = $dbh->prepare("select mode, size, name from .");
$sth->execute;
$sth->fetchrow_hashref; |
| XS::Parse::Infix versions from 0.40 through 0.49 for Perl treat a number as an array reference.
The wrapper function XS::Parse::Infix generates for a list-associative infix operator checks whether arguments are array references, but it tests using SvRV() rather than SvROK(). SvRV() reads a union slot that only holds a referent once SvROK(sv) is true, so the guard never validates that it is a reference. For an IV or NV that slot holds the number itself, SvRV() returns the caller's value and SvTYPE() dereferences it at offset 12. This will generally result in a segmentation fault.
An application that hands the wrapper a list built from decoded input (for example, from JSON) lets whoever supplies a number in that list choose the address that the interpreter dereferences.
An ordinary string's byte 12 is rarely SVt_PVAV so the guard croaks by luck, but an attacker-crafted string carrying 0x0b there passes, and the buffer is then used as an AV head, with AvARRAY taken from bytes 16-23 and its entries pushed onto the Perl stack as live SVs.
A simple proof-of-concept uses the zip operator:
use Syntax::Operator::Zip 'zip';
my @args = ([1], 2);
zip(@args); |
| Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, Suricata's IP defragmentation tracker lookup did not verify that an existing tracker used the same IP address family as the packet being processed. Under crafted fragmented IPv4/IPv6 traffic, an IPv6 fragment could be associated with an IPv4 defragmentation tracker. This can lead to a remote packet-triggered crash and denial of service when Suricata performs the relevant defragmentation. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, if using Suricata as an IDS with AF_PACKET, enabling AF_PACKET's `defrag` option may prevent Suricata from seeing such fragmented packets. |
| libical 4.0.6 contains an incompatible function pointer in icalparameter_string_to_kind(). When parsing iCalendar data containing a parameterized property, the function passes icalparameter_compare_kind_map() to bsearch() through an incompatible comparator function pointer type. bsearch() invokes the callback through the mismatched type, resulting in undefined behavior and process termination, leading to 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. |
| In Wakapi before 2.17.6, the user caching service allows a lookup to be resolved in an unintended lookup context, leading to account takeover. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack()
The timestamp-only fast path dereferences the option stream as
*(__be32 *)ptr, which assumes 4-byte alignment that the TCP option
stream does not guarantee. Use get_unaligned_be32() instead, which
reads the value safely and already returns host byte order, so the
htonl() on the comparison constant can be dropped.
This matches the existing get_unaligned_be32() use later in the same
function. |
| Type confusion in V8 in Google Chrome prior to 152.0.7977.82 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High) |
| pgcollection is an open source extension to PostgreSQL. A type confusion issue in AWS pgcollection 2.0.0 through 2.1.1 might allow an authenticated remote user to execute arbitrary code as the postgres operating system user via crafted SQL statements that rely on mismatched type metadata in collection value retrieval and array conversion functions.
To remediate this issue, users should upgrade to version 2.1.2 or later. |
| Access of resource using incompatible type ('type confusion') in Windows Performance Monitor allows an authorized attacker to elevate privileges locally. |
| A maliciously constructed mail header could lead to multiple fields being parsed as one, or potential memory safety violations. This vulnerability was fixed in Thunderbird 156, Thunderbird 140.16, and Thunderbird 153.3. |
| Access of resource using incompatible type ('type confusion') in Windows Core Messaging allows an authorized attacker to elevate privileges locally. |
| Suricata before 8.0.7 has a DoH2 type confusion that can cause an invalid free, because cleanup code for the HTTP2 state is executed even though the actual state is HTTP1 (when there is a DoH2 request with an HTTP1 to HTTP2 upgrade). This requires app-layer.protocols.doh2 to be enabled, which is the default in 8.x versions. |
| Out-of-bounds Read, Function Call With Incorrect Number of Arguments, Access of Resource Using Incompatible Type ('Type Confusion') vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.3.0 before 7.3.1.6, from 6.1.2.21 before 6.1.*. |
| Out-of-bounds Read, Function Call With Incorrect Number of Arguments, Access of Resource Using Incompatible Type ('Type Confusion') vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.3.0 before 7.3.1.6. |
| Nexus Repository 3 contained a privilege escalation vulnerability in the REST privileges API. An authenticated user with permission to manage privileges could, under certain role configurations, escalate their own access to full administrator by exploiting a type-confusion flaw in the privilege update endpoint. |
| Untrusted pointer dereference in Windows Group Policy allows an authorized attacker to elevate privileges over a network. |
| Fluent Bit is a fast and lightweight logs, metrics, and traces processor for Linux, BSD, macOS, and Windows. From 0.11.0 until 5.0.8, plugins/out_forward/forward.c secure_forward_pong copies the server-controlled PONG[2] reason into the 32-byte stack buffer msg with memcpy without checking its MessagePack type or length. An attacker who controls or can impersonate an out_forward Secure Forward destination configured with Shared_Key or Empty_Shared_Key can send an oversized reason during the first handshake and overwrite stack control data. Protected builds reliably terminate, while builds without a stack canary or with a disclosure can allow remote code execution as the Fluent Bit process user. When the opt-in --supervisor mode is used, fork-only respawns preserve the canary and address layout, allowing repeated crash-or-survive probes to support code execution on a hardened build; ordinary exec-based or service-manager restarts do not preserve that state. This issue is fixed in version 5.0.8. |
