Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU8702
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-2017-1000254
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to out-of-bounds read when parsing a directory name when connecting to an FTP server. A remote attacker can trigger memory corruption, access arbitrary files and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
Update the affected packages.
net-misc/curl to version: 7.57.0
Gentoo Linux: All versions
External linkshttp://security.gentoo.org/glsa/201712-04
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Buffer over-read
EUVDB-ID: #VU8917
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-2017-1000257
CWE-ID:
CWE-126 - Buffer over-read
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 buffer overread in the IMAP handle. A remote attacker can return a specially crafted IMAP FETCH response, obtain potentially sensitive information from memory on the target
system or cause the target application using libcurl to crash.
Update the affected packages.
net-misc/curl to version: 7.57.0
Gentoo Linux: All versions

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
3) Buffer overflow
EUVDB-ID: #VU9458
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-2017-8816
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to buffer overflow in the NTLM authentication process. A remote unauthenticated attacker can use vectors involving long user and password fields, trigger memory corruption and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
Update the affected packages.
net-misc/curl to version: 7.57.0
Gentoo Linux: All versions

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Out-of-bounds read
EUVDB-ID: #VU9459
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-8817
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to redirect the target client to an arbitrary site.
The vulnerability exists due to out-of-bounds read in the FTP wildcard function (CURLOPT_WILDCARDMATCH). A remote unauthenticated attacker can use a string that ends with an '[' character, trigger out-of-bounds read and cause the target connected libcurl client to be redirected.
MitigationUpdate the affected packages.

No. We are not aware of malware exploiting this vulnerability.
5) Denial of service
EUVDB-ID: #VU9460
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-8818
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to too little memory is allocated for interfacing to an SSL library. A remote attacker can trigger a memory allocation error in SSL-related code and cause the application to crash.
MitigationUpdate the affected packages.
