Description

According to the version of the pcre packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  • pcregrep in PCRE before 8.38 mishandles the -q option for binary files, which might allow remote attackers to obtain sensitive information via a crafted file, as demonstrated by a CGI script that sends stdout data to a client.(CVE-2015-8393)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
