Vixie Cron before the 3.0pl1-133 Debian package allows local users to cause a denial of service (daemon crash) via a large crontab file because the calloc return value is not checked.
CVE-2019-9214 2 Debian, Wireshark 2 Debian Linux, Wireshark 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the RPCAP dissector could crash. This was addressed in epan/dissectors/packet-rpcap.c by avoiding an attempted dereference of a NULL conversation.
CVE-2019-9208 2 Debian, Wireshark 2 Debian Linux, Wireshark 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the TCAP dissector could crash. This was addressed in epan/dissectors/asn1/tcap/tcap.cnf by avoiding NULL pointer dereferences.
CVE-2019-9199 2 Fedoraproject, Podofo Project 2 Fedora, Podofo 2023-11-07 6.8 MEDIUM 8.8 HIGH
PoDoFo::Impose::PdfTranslator::setSource() in pdftranslator.cpp in PoDoFo 0.9.6 has a NULL pointer dereference that can (for example) be triggered by sending a crafted PDF file to the podofoimpose binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.
CVE-2019-8936 5 Fedoraproject, Hpe, Netapp and 2 more 6 Fedora, Hpux-ntp, Clustered Data Ontap and 3 more 2023-11-07 5.0 MEDIUM 7.5 HIGH

CVE-2019-8379 4 Advancemame, Debian, Fedoraproject and 1 more 6 Advancecomp, Debian Linux, Fedora and 3 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
An issue was discovered in AdvanceCOMP through 2.1. A NULL pointer dereference exists in the function be_uint32_read() located in endianrw.h. It can be triggered by sending a crafted file to a binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact when a victim opens a specially crafted file.
CVE-2019-8377 2 Broadcom, Fedoraproject 2 Tcpreplay, Fedora 2023-11-07 6.8 MEDIUM 7.8 HIGH
An issue was discovered in Tcpreplay 4.3.1. A NULL pointer dereference occurred in the function get_ipv6_l4proto() located at get.c. This can be triggered by sending a crafted pcap file to the tcpreplay-edit binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.
CVE-2019-8376 2 Broadcom, Fedoraproject 2 Tcpreplay, Fedora 2023-11-07 6.8 MEDIUM 7.8 HIGH
An issue was discovered in Tcpreplay 4.3.1. A NULL pointer dereference occurred in the function get_layer4_v6() located at get.c. This can be triggered by sending a crafted pcap file to the tcpreplay-edit binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.
CVE-2019-5010 4 Debian, Opensuse, Python and 1 more 7 Debian Linux, Leap, Python and 4 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted certificates to trigger this vulnerability.
CVE-2019-5008 1 Qemu 1 Qemu 2023-11-07 5.0 MEDIUM 7.5 HIGH
hw/sparc64/sun4u.c in QEMU 3.1.50 is vulnerable to a NULL pointer dereference, which allows the attacker to cause a denial of service via a device driver.
CVE-2019-3995 2 Elog Project, Fedoraproject 2 Elog, Fedora 2023-11-07 5.0 MEDIUM 7.5 HIGH
ELOG 3.1.4-57bea22 and below is affected by a denial of service vulnerability due to a NULL pointer dereference. A remote unauthenticated attacker can crash the ELOG server by sending a crafted HTTP GET request.
CVE-2019-3840 2 Opensuse, Redhat 2 Leap, Libvirt 2023-11-07 3.5 LOW 6.3 MEDIUM
A NULL pointer dereference flaw was discovered in libvirt before version 5.0.0 in the way it gets interface information through the QEMU agent. An attacker in a guest VM can use this flaw to crash libvirtd and cause a denial of service.
CVE-2019-20919 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 1.9 LOW 4.7 MEDIUM
An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference.
CVE-2019-20093 2 Fedoraproject, Podofo Project 2 Fedora, Podofo 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
The PoDoFo::PdfVariant::DelayedLoad function in PdfVariant.h in PoDoFo 0.9.6 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file, because of ImageExtractor.cpp.
CVE-2019-19722 2 Dovecot, Fedoraproject 2 Dovecot, Fedora 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
In Dovecot before 2.3.9.2, an attacker can crash a push-notification driver with a crafted email when push notifications are used, because of a NULL Pointer Dereference. The email must use a group address as either the sender or the recipient.
CVE-2019-19647 2 Fedoraproject, Radare 2 Fedora, Radare2 2023-11-07 6.8 MEDIUM 7.8 HIGH
radare2 through 4.0.0 lacks validation of the content variable in the function r_asm_pseudo_incbin at libr/asm/asm.c, ultimately leading to an arbitrary write. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted input.
CVE-2019-19462 5 Canonical, Debian, Linux and 2 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2023-11-07 4.9 MEDIUM 5.5 MEDIUM
relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of service (such as relay blockage) by triggering a NULL alloc_percpu result.
CVE-2019-19269 3 Debian, Fedoraproject, Proftpd 3 Debian Linux, Fedora, Proftpd 2023-11-07 4.0 MEDIUM 4.9 MEDIUM
An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. A dereference of a NULL pointer may occur. This pointer is returned by the OpenSSL sk_X509_REVOKED_value() function when encountering an empty CRL installed by a system administrator. The dereference occurs when validating the certificate of a client connecting to the server in a TLS client/server mutual-authentication setup.
CVE-2019-18838 1 Envoyproxy 1 Envoy 2023-11-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Envoy 1.12.0. Upon receipt of a malformed HTTP request without a Host header, it sends an internally generated "Invalid request" response. This internally generated response is dispatched through the configured encoder filter chain before being sent to the client. An encoder filter that invokes route manager APIs that access a request's Host header causes a NULL pointer dereference, resulting in abnormal termination of the Envoy process.
CVE-2019-18804 5 Canonical, Debian, Djvulibre Project and 2 more 5 Ubuntu Linux, Debian Linux, Djvulibre and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
DjVuLibre 3.5.27 has a NULL pointer dereference in the function DJVU::filter_fv at IW44EncodeCodec.cpp.
