Description
This security bulletin contains information about 2 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2017-2885)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber
The 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.
2) Out-of-bounds read (CVE-ID: CVE-2018-12910)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The 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.
