Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Privilege Escalation
EUVDB-ID: #VU811
Risk: Medium
CVSSv4.0: 2 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2016-1238
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a local user to obtain elevated privileges on the target system.
The vulnerability exists due to improper input validation. By sending and tricking the victim to load a specially crafted code a malicious user can cause arbitrary code execution that allows them to gain root privileges.
Successful exploitation of this vulnerability will result in arbitrary code execution that allows a local attacker to get elevated privilegs on the vulnerable system.
Mitigation
Update the affected packages.
Opensuse: 15.0
CPE2.3 External linkshttps://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Insecure search path in perl5-porters
EUVDB-ID: #VU273
Risk: Low
CVSSv4.0: 0.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2016-1238
CWE-ID:
CWE-427 - Uncontrolled Search Path Element
Exploit availability: No
DescriptionThe vulnerability allows a local user to potentially elevate privileges.
The vulnerability exists due to Perl 5 module loads modules from the includes directory array ("@INC") in which the last element is the current directory ("."). A local attacker can place specially crafted modules into world-writable directory and trick the victim to run arbitrary script from this directory.
Successful exploitation of this vulnerability may allow a local attacker to obtain elevated privileges on the system.
MitigationUpdate the affected packages.
Opensuse: 15.0

3) Improper input validation
EUVDB-ID: #VU16549
Risk: Low
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-15705
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists in Apache SpamAssassin, using HTML::Parser due to an the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed when an object and hook are setup into the begin and end tag event handlers. A remote attacker can supply certain unclosed tags in specially crafted emails that cause markup to be handled incorrectly leading to scan timeouts.
MitigationUpdate the affected packages.
Opensuse: 15.0
CPE2.3 External linkshttps://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Improper input validation
EUVDB-ID: #VU16310
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2018-11780
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a remote code execution bug in the PDFInfo plug-in when handling malicious input. A remote unauthenticated attacker can trick the victim into opening a specially crafted email message and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
Opensuse: 15.0

5) Code injection
EUVDB-ID: #VU16311
Risk: Low
CVSSv4.0: 7.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Clear]
CVE-ID: CVE-2018-11781
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to execute arbitrary code on the target system.
The vulnerability exists due to a code injection condition in the meta rule syntax that exists when rules are processed by the affected software. A local attacker can supply specially crafted data and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
