Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Cross-site scripting
EUVDB-ID: #VU32341
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2016-1899
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in the ui-blob handler in CGit before 0.12. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
MitigationInstall updates from vendor's repository.
Vulnerable software versionsFedora: 6.0
cgit: before 0.12-1.el6
CPE2.3 External linkshttps://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2016-5a818bd0c6
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) Cross-site scripting
EUVDB-ID: #VU32342
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2016-1900
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. The vulnerability allows remote attackers with permission to write to a repository to inject arbitrary HTTP headers and conduct HTTP response splitting attacks or cross-site scripting (XSS) attacks via newline characters in a filename.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
MitigationInstall updates from vendor's repository.

3) Buffer overflow
EUVDB-ID: #VU32343
Risk: High
CVSSv4.0: 8.1 [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:U/U:Amber]
CVE-ID: CVE-2016-1901
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
Integer overflow in the authenticate_post function in CGit before 0.12 allows remote attackers to have unspecified impact via a large value in the Content-Length HTTP header, which triggers a buffer overflow.
MitigationInstall updates from vendor's repository.
