CVE-2026-7598 1 Libssh2 1 Libssh2 2026-11-10 7.3 High
A security vulnerability has been detected in libssh2 up to 1.11.1. The impacted element is the function userauth_password of the file src/userauth.c. Such manipulation of the argument username_len/password_len leads to integer overflow. The attack may be launched remotely. The name of the patch is 256d04b60d80bf1190e96b0ad1e91b2174d744b1. A patch should be applied to remediate this issue.
CVE-2026-57433 2 Haarg, Nwclark 2 Storable, Storable 2026-11-10 9.8 Critical
Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record. retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value. A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.
CVE-2026-57432 2 Perl, Shay 2 Perl, Perl 2026-11-10 8.4 High
Perl versions before 5.40.5-RC1, from 5.41.0 before 5.42.3-RC1, from 5.43.0 before 5.43.11 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack. S_measure_struct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes then guard their moves with a signed length comparison that passes when the length is negative, advancing the buffer pointer out of bounds. A template derived from untrusted input can read heap memory past the buffer and return it to the caller.

CVE-2026-56406 1 Libexpat Project 1 Libexpat 2026-11-10 6.9 Medium
libexpat before 2.8.2 has an integer overflow in XML_ParseBuffer because it lacked a check that was present in XML_Parse.
CVE-2026-56405 1 Libexpat Project 1 Libexpat 2026-11-10 6.9 Medium
libexpat before 2.8.2 has an integer overflow in getAttributeId.
CVE-2026-56404 1 Libexpat Project 1 Libexpat 2026-11-10 6.9 Medium
libexpat before 2.8.2 has an integer overflow in addBinding.
CVE-2026-56403 1 Libexpat Project 1 Libexpat 2026-11-10 6.9 Medium
libexpat before 2.8.2 has an integer overflow in storeAtts.
CVE-2026-25210 1 Libexpat Project 1 Libexpat 2026-11-10 6.9 Medium
In libexpat before 2.7.4, the doContent function does not properly determine the buffer size bufSize because there is no integer overflow check for tag buffer reallocation.
CVE-2026-13221 2 Perl, Shay 2 Perl, Perl 2026-11-10 9.1 Critical
Perl versions before 5.40.5-RC1, from 5.41.0 before 5.42.3-RC1, from 5.43.0 before 5.43.10 produce silently incorrect regular expression matches when an alternation of more than 65535 fixed string branches is compiled into a trie in Perl_study_chunk. When such branches are combined into a trie, the delta between the first branch and the shared tail is stored in a 16-bit field. A branch count above 65535 overflows the field, and the trie's match decision table is truncated with no warning or error. A pattern of this shape produces false positive matches (matching strings it should not) and false negative matches (failing to match strings it should). When such a pattern gates an access or filtering decision, the result is wrong.
CVE-2026-102633 2 Libexpat, Libexpat Project 2 Expat, Libexpat 2026-11-10 5.9 Medium
libexpat versions 2.7.2 through 2.8.5 contain an integer overflow vulnerability in expat_realloc() function on 32-bit platforms when computing allocation sizes. Attackers supplying malicious XML to applications parsing with vulnerable libexpat can cause heap buffer overflow, memory corruption, or denial of service.
CVE-2026-123370 1 Tmatens 1 Compose-lint 2026-11-10 N/A
compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.9.0 until 0.18.0, compose-lint's YAML parser recognizes lone carriage returns and Unicode line separators U+0085, U+2028, and U+2029 as line breaks while fix position conversion counts only newline characters. A pull request can place one of these separators in a quoted value so fix --apply shifts each later edit and deletes the line after the selected target, including an unselected network or other security setting. The resulting Compose file can remain valid, post-edit checks can pass, and the command can report a successful fix even though the dry-run diff was the only place showing the extra deletion. This issue is fixed in version 0.18.0.
CVE-2026-96113 1 Microsoft 14 Windows 10 1607, Windows 10 1809, Windows Server 2012 and 11 more 2026-11-10 9.8 Critical
Heap-based buffer overflow in DNS Server allows an unauthorized attacker to execute code over a network.
CVE-2026-110714 1 Sahlberg 1 Libsmb2 2026-11-10 6.5 Medium
libsmb2 through 6.2 contains an integer underflow vulnerability in decode_acl that allows malicious SMB servers to trigger heap out-of-bounds reads via crafted security descriptors. Attackers controlling a server or intercepting unsigned sessions can send an AclSize below 8 in a QUERY_INFO reply, bypassing ACE bounds checks and crashing the client.
CVE-2026-62438 2 Red Hat, Redhat 3 Enterprise Linux, Enterprise Linux, Rhel Els 2026-11-10 6.1 Medium
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.
CVE-2026-70388 1 Rt-labs Ab 1 Soem 2026-11-10 8.3 High
SOEM version 2.0.0 and earlier contains vulnerabilities where a malicious device on the network can send specially crafted messages that cause the master to write data outside allocated memory boundaries. The software performs arithmetic on message length values without proper validation, allowing negative or extremely large values to bypass safety checks. This can corrupt memory and potentially allow an attacker to execute arbitrary code on the master system.
