BackBox Linux 4.6 allows remote attackers to cause a denial of service (ksoftirqd CPU consumption) via a flood of packets with Martian source IP addresses (as defined in RFC 1812 section 5.3.7). This product enables net.ipv4.conf.all.log_martians by default.
The ourWriteOut function in tool_writeout.c in curl 7.53.1 might allow physically proximate attackers to obtain sensitive information from process memory in opportunistic circumstances by reading a workstation screen during use of a –write-out argument ending in a ‘%’ character, which leads to a heap-based buffer over-read.
The fill_threshhold_buffer function in base/gxht_thresh.c in Artifex Software, Inc. Ghostscript 9.20 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document.
Small and medium-sized businesses (SMBs) are the biggest targets of cybercriminals, and they often don’t have the necessary budgets, people, processes, and products to protect themselves. Because of this, SMBs are increasingly turning their cybersecurity protection over to managed service providers (MSPs).
