CVE-2018-7452 1 Xpdfreader 1 Xpdf 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference in JPXStream::fillReadBuf in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service via a specific pdf file, as demonstrated by pdftohtml.
CVE-2018-7361 1 Zte 2 Zxhn F670, Zxhn F670 Firmware 2024-11-21 3.3 LOW 6.5 MEDIUM
All versions up to V1.1.10P3T18 of ZTE ZXHN F670 product are impacted by null pointer dereference vulnerability, which may allows an attacker to cause a denial of service via appviahttp service.
CVE-2018-7336 2 Debian, Wireshark 2 Debian Linux, Wireshark 2024-11-21 5.0 MEDIUM 7.5 HIGH
In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, the FCP protocol dissector could crash. This was addressed in epan/dissectors/packet-fcp.c by checking for a NULL pointer.
CVE-2018-7285 1 Digium 1 Asterisk 2024-11-21 5.0 MEDIUM 7.5 HIGH
A NULL pointer access issue was discovered in Asterisk 15.x through 15.2.1. The RTP support in Asterisk maintains its own registry of dynamic codecs and desired payload numbers. While an SDP negotiation may result in a codec using a different payload number, these desired ones are still stored internally. When an RTP packet was received, this registry would be consulted if the payload number was not found in the negotiated SDP. This registry was incorrectly consulted for all packets, even those which are dynamic. If the payload number resulted in a codec of a different type than the RTP stream (for example, the payload number resulted in a video codec but the stream carried audio), a crash could occur if no stream of that type had been negotiated. This was due to the code incorrectly assuming that a stream of that type would always exist.
CVE-2018-7262 2 Fedoraproject, Redhat 2 Fedora, Ceph 2024-11-21 5.0 MEDIUM 7.5 HIGH
In Ceph before 12.2.3 and 13.x through 13.0.1, the rgw_civetweb.cc RGWCivetWeb::init_env function in radosgw doesn't handle malformed HTTP headers properly, allowing for denial of service.
CVE-2018-7191 1 Linux 1 Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343.
CVE-2018-7175 1 Xpdfreader 1 Xpdf 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An issue was discovered in xpdf 4.00. A NULL pointer dereference in readCodestream allows an attacker to cause denial of service via a JPX image with zero components.
CVE-2018-7052 3 Canonical, Debian, Irssi 3 Ubuntu Linux, Debian Linux, Irssi 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Irssi before 1.0.7 and 1.1.x before 1.1.1. When the number of windows exceeds the available space, a crash due to a NULL pointer dereference would occur.
CVE-2018-7050 3 Canonical, Debian, Irssi 3 Ubuntu Linux, Debian Linux, Irssi 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Irssi before 1.0.7 and 1.1.x before 1.1.1. A NULL pointer dereference occurs for an "empty" nick.
CVE-2018-6972 2 Apple, Vmware 4 Mac Os X, Esxi, Fusion and 1 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
VMware ESXi (6.7 before ESXi670-201806401-BG, 6.5 before ESXi650-201806401-BG, 6.0 before ESXi600-201806401-BG and 5.5 before ESXi550-201806401-BG), Workstation (14.x before 14.1.2), and Fusion (10.x before 10.1.2) contain a denial-of-service vulnerability due to NULL pointer dereference issue in RPC handler. Successful exploitation of this issue may allow attackers with normal user privileges to crash their VMs.
CVE-2018-6963 1 Vmware 2 Fusion, Workstation 2024-11-21 2.1 LOW 5.5 MEDIUM
VMware Workstation (14.x before 14.1.2) and Fusion (10.x before 10.1.2) contain multiple denial-of-service vulnerabilities that occur due to NULL pointer dereference issues in the RPC handler. Successful exploitation of these issues may allow an attacker with limited privileges on the guest machine trigger a denial-of-Service of their guest machine.
CVE-2018-6951 2 Canonical, Gnu 2 Ubuntu Linux, Patch 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a "mangled rename" issue.
CVE-2018-6942 2 Canonical, Freetype 2 Ubuntu Linux, Freetype 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in FreeType 2 through 2.9. A NULL pointer dereference in the Ins_GETVARIATION() function within ttinterp.c could lead to DoS via a crafted font file.
CVE-2018-6925 1 Freebsd 1 Freebsd 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In FreeBSD before 11.2-STABLE(r338986), 11.2-RELEASE-p4, 11.1-RELEASE-p15, 10.4-STABLE(r338985), and 10.4-RELEASE-p13, due to improper maintenance of IPv6 protocol control block flags through various failure paths, an unprivileged authenticated local user may be able to cause a NULL pointer dereference causing the kernel to crash.
CVE-2018-6644 1 Sblim Project 1 Small Footprint Cim Broker 2024-11-21 5.0 MEDIUM 7.5 HIGH
SBLIM Small Footprint CIM Broker (SFCB) 1.4.9 has a null pointer (DoS) vulnerability via a crafted POST request to the /cimom URI.
CVE-2018-6534 1 Icinga 1 Icinga 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Icinga 2.x through 2.8.1. By sending specially crafted messages, an attacker can cause a NULL pointer dereference, which can cause the product to crash.
CVE-2018-6319 1 Sophos 1 Sophos Tester 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In Sophos Tester Tool 3.2.0.7 Beta, the driver accepts a special DeviceIoControl code that doesn't check its argument. This argument is a memory address: if a caller passes a NULL pointer or a random invalid address, the driver will cause a Blue Screen of Death. If a program or malware does this at boot time, it can cause a persistent denial of service on the machine.
