The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:14910-1 advisory.

  - 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 >& fd syntax.
    (CVE-2014-10071)

  - In utils.c in zsh before 5.0.6, there is a buffer overflow when scanning very long directory paths for     symbolic links. (CVE-2014-10072)

  - In zsh before 5.3, an off-by-one error resulted in undersized buffers that were intended to support     PATH_MAX characters. (CVE-2016-10714)

  - 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)

  - In utils.c in zsh before 5.4, symlink expansion had a buffer overflow. (CVE-2017-18206)

  - An issue was discovered in zsh before 5.6. The beginning of a #! script file was mishandled, potentially     leading to an execve call to a program named on the second line. (CVE-2018-0502)

  - 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)

  - Zsh before version 5.4.2-test-1 is vulnerable to a buffer overflow in the shell autocomplete     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 autocomplete to traverse the before mentioned path.
    If the user affected is privileged, this leads to privilege escalation. (CVE-2018-1083)

  - An issue was discovered in zsh before 5.6. Shebang lines exceeding 64 characters were truncated,     potentially leading to an execve call to a program name that is a substring of the intended one.
    (CVE-2018-13259)

  - 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)

  - In Zsh before 5.8, attackers able to execute commands can regain privileges dropped by the --no-PRIVILEGED     option. Zsh fails to overwrite the saved uid, so the original privileges can be restored by executing     MODULE_PATH=/dir/with/module zmodload with a module that calls setuid(). (CVE-2019-20044)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
