An update that fixes 5 vulnerabilities is now available.
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)
