Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU7882
Risk: Low
CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-1000099
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to obtain potentially sensitive information.
The weakness exists due to out-of bounds read. A local attacker can load a specially crafted 'file://' URL to cause the curl application to return data from system memory.
Successful exploitation of the vulnerability results in information disclosure.
Update the affected package curl to version 7.55-1.
Vulnerable software versionsArch Linux: All versions
CPE2.3 External linkshttps://security.archlinux.org/advisory/ASA-201708-16
Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Open redirect
EUVDB-ID: #VU7884
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-1000100
CWE-ID:
CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to redirect website visitors to external websites.
