CVSS: 6.5EPSS: 0%CPEs: 9EXPL: 0CVE-2023-36054 – krb5: Denial of service through freeing uninitialized pointer
https://notcve.org/view.php?id=CVE-2023-36054
lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. A vulnerability was found in the _xdr_kadm5_principal_ent_rec() function in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (krb5). This issue occurs due to lack of validation in the relationship between n_key_data and the key_data array count, leading to the freeing of uninitialized pointers. • https://github.com/krb5/krb5/commit/ef08b09c9459551aabbe7924fb176f1583053cdd https://github.com/krb5/krb5/compare/krb5-1.20.1-final...krb5-1.20.2-final https://github.com/krb5/krb5/compare/krb5-1.21-final...krb5-1.21.1-final https://lists.debian.org/debian-lts-announce/2023/10/msg00031.html https://security.netapp.com/advisory/ntap-20230908-0004 https://web.mit.edu/kerberos/www/advisories https://access.redhat.com/security/cve/CVE-2023-36054 https://bugzilla.redhat.com&#x • CWE-824: Access of Uninitialized Pointer •
CVSS: 7.5EPSS: 0%CPEs: 21EXPL: 0CVE-2023-3107 – Remote denial of service in IPv6 fragment reassembly
https://notcve.org/view.php?id=CVE-2023-3107
A set of carefully crafted ipv6 packets can trigger an integer overflow in the calculation of a fragment reassembled packet's payload length field. This allows an attacker to trigger a kernel panic, resulting in a denial of service. Un conjunto de paquetes ipv6 cuidadosamente diseñados puede desencadenar un desbordamiento de enteros en el cálculo del campo de longitud de la carga útil de un paquete reensamblado por fragmentos. Esto permite a un atacante desencadenar un kernel panic, resultando en una denegación de servicio. • https://security.FreeBSD.org/advisories/FreeBSD-SA-23:06.ipv6.asc https://security.netapp.com/advisory/ntap-20230804-0001 • CWE-190: Integer Overflow or Wraparound •
CVSS: 7.5EPSS: 0%CPEs: 9EXPL: 0CVE-2023-38403 – iperf3: memory allocation hazard and crash
https://notcve.org/view.php?id=CVE-2023-38403
iperf3 before 3.14 allows peers to cause an integer overflow and heap corruption via a crafted length field. An integer overflow flaw was found in the way iperf3 dynamically allocates memory buffers for JSON-formatted messages. A remote attacker could send a specially crafted sequence of bytes on the iperf3 control channel with a specified JSON message length of 0xffffffff to trigger an integer overflow leading the receiving process to abort due to heap corruption. This flaw allows an attacker to use a malicious client to cause a denial of service of an iperf3 server or potentially use a malicious server to cause connecting clients to crash. • http://seclists.org/fulldisclosure/2023/Oct/24 http://seclists.org/fulldisclosure/2023/Oct/26 https://bugs.debian.org/1040830 https://cwe.mitre.org/data/definitions/130.html https://downloads.es.net/pub/iperf/esnet-secadv-2023-0001.txt.asc https://github.com/esnet/iperf/commit/0ef151550d96cc4460f98832df84b4a1e87c65e9 https://github.com/esnet/iperf/issues/1542 https://lists.debian.org/debian-lts-announce/2023/07/msg00025.html https://lists.fedoraproject.org/archives/list/package-announce% • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2023-2953
A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function. A vulnerability was found in OpenLDAP, in ber_memalloc_x() function, leading to a null pointer dereference. This flaw can result in reduced system memory and cause LDAP authentication failures. The impact is primarily a disruption in authentication processes, which may hinder user access or service operations relying on LDAP for authentication. • http://seclists.org/fulldisclosure/2023/Jul/47 http://seclists.org/fulldisclosure/2023/Jul/48 http://seclists.org/fulldisclosure/2023/Jul/52 https://access.redhat.com/security/cve/CVE-2023-2953 https://bugs.openldap.org/show_bug.cgi?id=9904 https://security.netapp.com/advisory/ntap-20230703-0005 https://support.apple.com/kb/HT213843 https://support.apple.com/kb/HT213844 https://support.apple.com/kb/HT213845 https://bugzilla.redhat.com/show_bug.cgi?id=2210651 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2023-27537
A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. • https://hackerone.com/reports/1897203 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0010 • CWE-415: Double Free •
