Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Stack-based buffer overflow
EUVDB-ID: #VU7866
Risk: High
CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2017-2885
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the in the libsoup library for GNOME due to improper bounds checking when processing a crafted HTTP request containing chunk encoded data. A remote attacker can send a specially crafted HTTP request, trigger a stack-based buffer overflow condition in the soup_body_input_stream_read_chunked function in the libsoup/soup-body-input-stream.c code and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.

2) Out-of-bounds read
EUVDB-ID: #VU13598
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-2018-12910
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information or cause DoS condition on the target system.
The weakness exists due to insufficient validation of cookie requests. A remote attacker can supply specially crafted cookie request, trigger out-of-bounds memory read and gain access to arbitrary data or cause the service to crash.
Update the affected packages.
