This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 8.3.1. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the modDate attribute of Annotation objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code under the context of the current process. Was ZDI-CAN-5028.
Search vulnerabilities
The netjoin processing in Irssi 1.x before 1.0.2 allows attackers to cause a denial of service (use-after-free) and possibly execute arbitrary code via unspecified vectors.
An issue was discovered in Contiki Operating System 3.0. A use-after-free vulnerability exists in httpd-simple.c in cc26xx-web-demo httpd, where upon a connection close event, the http_state structure was not deallocated properly, resulting in a NULL pointer dereference in the output processing function. This resulted in a board crash, which can be used to perform denial of service.
In Android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, due to a race condition in the GLink kernel driver, a Use After Free condition can potentially occur.
Kernel: kvm: use after free in complete_emulated_mmio
arch/x86/kvm/emulate.c in the Linux kernel through 4.9.3 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free) via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt.
libical: Multiple use-after-free vulnerabilities
libical 1.0 allows remote attackers to cause a denial of service (use-after-free) via a crafted ics file.
exim: use-after-free in receive_msg function via vectors involving BDAT commands
The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via vectors involving BDAT commands.
An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "IOHIDFamily" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (use-after-free) via a crafted app.
openvpn: Multiple security issues fixed in OpenVPN 2.4.3 and 2.3.17
OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to remote denial-of-service due to memory exhaustion caused by memory leaks and double-free issue in extract_x509_extension().
An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. tvOS before 10.2 is affected. watchOS before 3.2 is affected. The issue involves the "Kernel" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (use-after-free) via a crafted app.
An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability is an instance of a use after free vulnerability in the MakeAccessible plugin, when creating an internal data structure. The mismatch between an old and a new object can provide an attacker with unintended memory access -- potentially leading to code corruption, control-flow hijack, or an information leak attack. Successful exploitation could lead to arbitrary code execution.
An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. iCloud before 6.2 on Windows is affected. iTunes before 12.6 on Windows is affected. tvOS before 10.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.
An issue was discovered in certain Apple products. macOS before 10.12.4 is affected. The issue involves the "Bluetooth" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (use-after-free) via a crafted app.
openldap: Double free vulnerability in servers/slapd/back-mdb/search.c
servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user with access to search the directory can crash slapd by issuing a search including the Paged Results control with a page size of 0.
rkhunter versions before 1.4.4 are vulnerable to file download over insecure channel when doing mirror update resulting into potential remote code execution.
kernel: Double fetch in the intr function in sound/oss/msnd_pinnacle.c
The intr function in sound/oss/msnd_pinnacle.c in the Linux kernel through 4.11.7 allows local users to cause a denial of service (over-boundary access) or possibly have unspecified other impact by changing the value of a message queue head pointer between two kernel reads of that value, aka a "double fetch" vulnerability.
An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. watchOS before 3.2 is affected. The issue involves the "WebKit" component. A use-after-free vulnerability allows remote attackers to execute arbitrary code via a crafted web site.
collectd: double free in csnmp_read_table function in snmp.c
The csnmp_read_table function in snmp.c in the SNMP plugin in collectd before 5.6.3 is susceptible to a double free in a certain error case, which could lead to a crash (or potentially have other impact).
kernel: Handling of might_cancel queueing is not properly pretected against race
Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing.
jasper: incorrect handling of bufsize 0 in mem_resize()
Double free vulnerability in the mem_close function in jas_stream.c in JasPer before 1.900.10 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted BMP image to the imginfo command.
