Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Security restrictions bypass
EUVDB-ID: #VU11343
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10545
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to bypass security restrictions and obtain potentially sensitive information on the target system.
The weakness exists due to improper access controls. A local attacker can change UID and GID, PHP-FPM sets pool worker processes to be dumpable, attach to the PHP-FPM workers and gain access to any restricted resources that are not supposed to be allowed.
Update the affected packages.
Opensuse: 42.3

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) Infinite loop
EUVDB-ID: #VU12257
Risk: Low
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2018-10546
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to infinite loop. A remote attacker can use a stream filter with convert.iconv and not enough input bytes, trigger an infinite loop, one CPU Core at 100% and cause the service to crash.
Update the affected packages.
Opensuse: 42.3

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. However, proof of concept for this vulnerability is available.
3) Cross-site scripting
EUVDB-ID: #VU12327
Risk: Low
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10547
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists in the phar_do_404() and phar_do_403() functions due to insufficient sanitization of user-supplied data processed by the phar_do_404() and phar_do_403() functions, as defined in the ext/phar/phar_object.c source code file. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
The vulnerability exists due to an incomplete fix for CVE-2018-5712.
MitigationUpdate the affected packages.

No. We are not aware of malware exploiting this vulnerability.
4) Man-in-the-middle attack
EUVDB-ID: #VU12256
Risk: Low
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-10548
CWE-ID:
CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the ext/ldap/ldap.c source code file due to improper handling of return values from the ldap_get_dn function. A remote attacker can use man-in-the middle techniques to trigger ldap_get_dn() to return a NULL pointer and cause ldap_get_entries() because add_assoc_string() to crash.
Update the affected packages.
