Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Man-in-the-middle attack
EUVDB-ID: #VU12256
Risk: Low
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
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.

No. We are not aware of malware exploiting this vulnerability.
2) Use-after-free error
EUVDB-ID: #VU13498
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-2018-12882
CWE-ID:
CWE-416 - Use After Free
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 use-after-free error when the exif_read_from_impl function, as defined in the ext/exif/exif.c source code file, closes a stream that it is not responsible for closing. A remote unauthenticated attacker can trick the victim into opening a specially crafted file that submits malicious .jpeg input, trigger memory corruption 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.
