EulerOS 2.0 SP5 : ruby (EulerOS-SA-2019-1990)

critical Nessus Plugin ID 129184

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A SMTP command injection flaw was found in the way Ruby's Net::SMTP module handled CRLF sequences in certain SMTP commands. An attacker could potentially use this flaw to inject SMTP commands in a SMTP session in order to facilitate phishing attacks or spam campaigns.(CVE-2015-9096)

- An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer.(CVE-2017-9224)

- An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A heap out-of-bounds write occurs in bitset_set_range() during regular expression compilation due to an uninitialized variable from an incorrect state transition. An incorrect state transition in parse_char_class() could create an execution path that leaves a critical local variable uninitialized until it's used as an index, resulting in an out-of-bounds write memory corruption.(CVE-2017-9228)

- An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching.
Invalid handling of reg-i1/4zdmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer.(CVE-2017-9227)

- An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg-i1/4zdmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition.(CVE-2017-9229)

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

Solution

Update the affected ruby packages.
