Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
1) Integer overflow
EUVDB-ID: #VU16183
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-18311
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in Perl_my_setenv when processing malicious input. A remote unauthenticated attacker can supply specially crafted data, trigger heap-based buffer overflow and cause the service to crash or execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
dev-lang/perl to version: 5.28.2

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

5) Heap-based buffer overflow
EUVDB-ID: #VU11833
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-6797
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists in S_regatom() in 'regcomp.c' due to heap-based buffer overflow. A local attacker can exploit a specially crafted regular expression, trigger memory corruption and cause the service to crash or run Perl code.
