SUSE SLED12 / SLES12 Security Update : procps (SUSE-SU-2018:1836-1)

High Nessus Plugin ID 110804

Synopsis

The remote SUSE host is missing one or more security updates.

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-based 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).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
