Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU11111
Risk: High
CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1000120
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to heap-based buffer overflow. A remote attacker that can control the paths that curl uses for FTP can create specially crafted path names containing the control characters '%00', trigger memory corruption and execute arbitrary code.
Update the affected package lib32-libcurl-gnutls to version 7.59.0-1.

2) Null pointer dereference
EUVDB-ID: #VU11105
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1000121
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to NULL pointer dereference in ldap_get_attribute_ber(). A remote attacker can return a specially crafted redirect to an LDAP URL, trigger NULL pointer dereference and cause the service to crash.//
Update the affected package lib32-libcurl-gnutls to version 7.59.0-1.

3) Buffer over-read
EUVDB-ID: #VU11108
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-1000122
CWE-ID:
CWE-126 - Buffer over-read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition.
The weakness exists due to buffer over-read. A remote attacker can cause the target application to trigger a buffer copy
error in processing RTSP URLs and cause the application to crash or
access potentially sensitive information on the target system.
Update the affected package lib32-libcurl-gnutls to version 7.59.0-1.
