Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU10223

Risk: Low

CVSSv4.0: 2.7 [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]

CVE-ID: CVE-2018-1000005

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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 user-supplied input. A remote attacker can send a specially crafted HTTP/2 trailer to trigger an out-of-bounds memory read error and cause the application to crash or obtain potentially sensitive information from services that echo back or otherwise use the trailers.

Mitigation

Update the affected package lib32-libcurl-gnutls to version 7.58.0-1.

Vulnerable software versions

Arch Linux: All versions

2) Information disclosure

EUVDB-ID: #VU10224

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-1000007

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can send custom headers in an HTTP request and an HTTP 30X redirect response code, cause the application to send the custom headers to the server specified in the 'Location:' response header and  obtain potentially sensitive authentication information from applications that use custom 'Authorization:' headers.

Mitigation

Update the affected package lib32-libcurl-gnutls to version 7.58.0-1.
