Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Cryptographic issues
EUVDB-ID: #VU32619
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2013-4508
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to read and manipulate data.
lighttpd before 1.4.34, when SNI is enabled, configures weak SSL ciphers, which makes it easier for remote attackers to hijack sessions by inserting packets into the client-server data stream or obtain sensitive information by sniffing the network. Per: http://download.lighttpd.net/lighttpd/security/lighttpd_sa_2013_01.txt "All versions from 1.4.24 (first version supporting SNI) up to and including 1.4.33."
MitigationInstall updates from vendor's repository.

2) Use-after-free
EUVDB-ID: #VU32621
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2013-4560
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing unspecified vectors that trigger FAMMonitorDirectory failures. A remote attackers can cause a denial of service (segmentation fault and crash).
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

3) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU32620
Risk: High
CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2013-4559
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
lighttpd before 1.4.33 does not check the return value of the (1) setuid, (2) setgid, or (3) setgroups functions, which might cause lighttpd to run as root if it is restarted and allows remote attackers to gain privileges, as demonstrated by multiple calls to the clone function that cause setuid to fail when the user process limit is reached.
MitigationInstall updates from vendor's repository.
