       An update that fixes 5 vulnerabilities is now available.
    
    Description:
    
    
    
       This update for procps fixes the following security issues:
    
       - CVE-2018-1122: Prevent local privilege escalation in top. If a user ran
         top with HOME unset in an attacker-controlled directory, the attacker
         could have achieved privilege escalation by exploiting one of several
         vulnerabilities in the config_file() function (bsc#1092100).
       - CVE-2018-1123: Prevent denial of service in ps via mmap buffer overflow.
         Inbuilt protection in ps maped a guard page at the end of the overflowed
         buffer, ensuring that the impact of this flaw is limited to a crash
         (temporary denial of service) (bsc#1092100).
       - CVE-2018-1124: Prevent multiple integer overflows leading to a heap
         corruption in file2strvec function. This allowed a privilege escalation
         for a local attacker who can create entries in procfs by starting
         processes, which could result in crashes or arbitrary code execution in
         proc utilities run by
         other users (bsc#1092100).
       - CVE-2018-1125: Prevent stack buffer overflow in pgrep. This
         vulnerability was mitigated by FORTIFY limiting the impact to a crash
         (bsc#1092100).
       - CVE-2018-1126: Ensure correct integer size in proc/alloc.* to prevent
         truncation/integer overflow issues (bsc#1092100).
    
       (These issues were previously released for SUSE Linux Enterprise 12 SP3
       and SP4.)
    
       Also the following non-security issue was fixed:
    
       - Fix CPU summary showing old data. (bsc#1121753)
