"A buffer overflow flaw was found in the zsh shell symbolic link

directory path which leads to a buffer overflow in the context of the
user trying to do a symbolic link resolution in the aforementioned
path. If the user affected is privileged, this leads to privilege
escalation.(CVE-2017-18206)

A buffer overflow flaw was found in the zsh shell auto-complete
functionality. A local, unprivileged user can create a specially
crafted directory path which leads to code execution in the context of
the user who tries to use auto-complete to traverse the before
mentioned path. If the user affected is privileged, this leads to
privilege escalation.(CVE-2018-1083)

A NULL pointer dereference flaw was found in the code responsible for
saving hashtables of the zsh package. An attacker could use this flaw
to cause a denial of service by crashing the user
shell.(CVE-2018-7549)

A NULL pointer dereference flaw was found in the code responsible for
the cd builtin command of the zsh package. An attacker could use this
flaw to cause a denial of service by crashing the user
shell.(CVE-2017-18205)

A buffer overflow flaw was found in the zsh shell symbolic link
resolver. A local, unprivileged user can create a specially crafted
directory path which leads to a buffer overflow in the context of the
user trying to do symbolic link resolution in the aforementioned path.
An attacker could exploit this vulnerability to cause a denial of
service condition on the target.(CVE-2014-10072)

A buffer overflow flaw was found in the zsh shell check path
functionality. A local, unprivileged user can create a specially
crafted message file, which, if used to set a custom 'you have new
mail' message, leads to code execution in the context of the user who
receives the message. If the user affected is privileged, this leads
to privilege escalation.(CVE-2018-1100)

zsh through version 5.4.2 is vulnerable to a stack-based buffer
overflow in the exec.c:hashcmd() function. A local attacker could
exploit this to cause a denial of service.(CVE-2018-1071)

A buffer overflow flaw was found in the zsh shell file descriptor
redirection functionality. An attacker could use this flaw to cause a
denial of service by crashing the user shell.(CVE-2014-10071)"

"According to the versions of the zsh package installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

  - The zsh shell is a command interpreter usable as an
    interactive login shell and as a shell script command
    processor. Zsh resembles the ksh shell (the Korn
    shell), but includes many enhancements. Zsh supports
    command line editing, built-in spelling correction,
    programmable command completion, shell functions (with
    autoloading), a history mechanism, and more.

  - Security fix(es):

  - In builtin.c in zsh before 5.4, when sh compatibility
    mode is used, there is a NULL pointer dereference
    during processing of the cd command with no argument if
    HOME is not set.(CVE-2017-18205)

  - zsh before 5.0.7 allows evaluation of the initial
    values of integer variables imported from the
    environment (instead of treating them as literal
    numbers). That could allow local privilege escalation,
    under some specific and atypical conditions where zsh
    is being invoked in privilege-elevation contexts when
    the environment has not been properly sanitized, such
    as when zsh is invoked by sudo on systems where
    'env_reset' has been disabled.(CVE-2014-10070)

  - In exec.c in zsh before 5.0.7, there is a buffer
    overflow for very long fds in the 'i1/4zi1/4+ fd'
    syntax.(CVE-2014-10071)

  - A buffer overflow flaw was found in the zsh shell
    symbolic link resolver. A local, unprivileged user can
    create a specially crafted directory path which leads
    to a buffer overflow in the context of the user trying
    to do a symbolic link resolution in the aforementioned
    path. If the user affected is privileged, this leads to
    privilege escalation.(CVE-2017-18206)

  - In params.c in zsh through 5.4.2, there is a crash
    during a copy of an empty hash table, as demonstrated
    by typeset -p.(CVE-2018-7549)

  - A buffer overflow flaw was found in the zsh shell file

    use this flaw to cause a denial of service by crashing
    the user shell. (CVE-2014-10071)

  - A NULL pointer dereference flaw was found in the code

    package. An attacker could use this flaw to cause a
    denial of service by crashing the user shell.
    (CVE-2017-18205)

  - A buffer overflow flaw was found in the zsh shell check
    path functionality. A local, unprivileged user can
    create a specially crafted message file, which, if used
    to set a custom you have new mail message, leads to
    code execution in the context of the user who receives
    the message. If the user affected is privileged, this
    leads to privilege escalation. (CVE-2018-1100)

  - A buffer overflow flaw was found in the zsh shell auto-
    complete functionality. A local, unprivileged user can
    create a specially crafted directory path which leads to
    code execution in the context of the user who tries to
    use auto-complete to traverse the before mentioned path.
    If the user affected is privileged, this leads to
    privilege escalation. (CVE-2018-1083)

  - zsh through version 5.4.2 is vulnerable to a stack-based
    buffer overflow in the exec.c:hashcmd() function. A
    local attacker could exploit this to cause a denial of
    service. (CVE-2018-1071)

  - A NULL pointer dereference flaw was found in the code
    responsible for saving hashtables of the zsh package. An
    attacker could use this flaw to cause a denial of
    service by crashing the user shell. (CVE-2018-7549)

  - A buffer overflow flaw was found in the zsh shell
    symbolic link resolver. A local, unprivileged user can
    create a specially crafted directory path which leads to
    a buffer overflow in the context of the user trying to
    do a symbolic link resolution in the aforementioned
    path. If the user affected is privileged, this leads to

    symbolic link resolver. A local, unprivileged user can
    create a specially crafted directory path which leads to
    a buffer overflow in the context of the user trying to
    do symbolic link resolution in the aforementioned path.
    An attacker could exploit this vulnerability to cause a
    denial of service condition on the target.
