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)

This update was imported from the SUSE:SLE-12:Update update project.
