openSUSE Security Update: Security update for procps

Announcement ID: openSUSE-SU-2018:1848-1
Rating: moderate
References: #1092100
Cross-References: CVE-2018-1122 CVE-2018-1123 CVE-2018-1124
CVE-2018-1125 CVE-2018-1126
Affected Products:
openSUSE Leap 42.3

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
– CVE-2018-1126: Ensure correct integer size in proc/alloc.* to prevent
truncation/integer overflow issues (bsc#1092100).

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