Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU16783
Risk: Low
CVSSv3.1: 3.4 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-20483
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain access to potentially sensitive information.
The vulnerability exists due to set_file_metadata in xattr.c stores a file's origin URL in the user.xdg.origin.url metadata attribute of the extended attributes of the downloaded file. A local attacker can read this attribute, as demonstrated by getfattr and obtain credentials contained in the URL.
MitigationUpdate the affected packages.

EUVDB-ID: #VU13841
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-2018-0500
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 vulnerability exists in curl_smtp_escape_eob in lib/smtp.c due to heap-based buffer overflow when a system invokes curl to send data via SMTP and uses a reduced read buffer. A remote unauthenticated attacker can trigger memory corruption and cause the service to crash or execute arbitrary data with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
