According to the versions of the zsh package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
zsh: buffer overflow for very long fds in i1/4zi1/4+ fd syntax (CVE-2014-10071)
zsh: buffer overflow when scanning very long directory paths for symbolic links (CVE-2014-10072)
zsh: NULL dereference in cd in sh compatibility mode under given circumstances (CVE-2017-18205)
zsh: buffer overrun in symlinks (CVE-2017-18206)
zsh: Stack-based buffer overflow in exec.c:hashcmd() (CVE-2018-1071)
zsh: buffer overflow in utils.c:checkmailpath() can lead to local arbitrary code execution (CVE-2018-1100)
zsh: crash on copying empty hash table (CVE-2018-7549)
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.
