Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Man-in-the-middle attack (CVE-ID: CVE-2018-10548)

The 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.

2) Use-after-free error (CVE-ID: CVE-2018-12882)

The 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.
