Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Deserialization of untrusted data

EUVDB-ID: #VU10334

Risk: Low

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-9138

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to unsafe handling of serialized data when processing property modification during __wakeup(). A remote attacker can pass specially crafted serialized data to the application and cause denial of service attack.

Mitigation

Update the affected package to version: 5.6.28+dfsg-0+deb8u1

Vulnerable software versions

Debian 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.

2) Resource exhaustion

EUVDB-ID: #VU12901

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-9933

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the gdImageFillToBorder function in gd.c due to stack consumption. A remote attacker can submit a specially crafted imagefilltoborder call that triggers use of a negative color value and cause the service to crash.

Mitigation

Update the affected package to version: 5.6.28+dfsg-0+deb8u1

Vulnerable software versions

Debian Linux: All versions

3) NULL pointer dereference

EUVDB-ID: #VU12902

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2016-9934

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in ext/wddx/wddx.c due to NULL pointer dereference. A remote attacker can submit crafted serialized data in a wddxPacket XML document, as demonstrated by a PDORow string, and cause the service to crash.

Mitigation

Update the affected package to version: 5.6.28+dfsg-0+deb8u1
