Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU10326

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-2017-1000456

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 weakness exists due to improper validation of boundaries in TextPool::addWord in freedesktop.org libpoppler. A remote attacker can trigger overflow in subsequent calculations and cause the service to crash.

Mitigation

Update the affected packages.
app-text/poppler to version: 0.61.1

Vulnerable software versions

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.

2) NULL pointer derefenrece

EUVDB-ID: #VU8651

Risk: Low

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-14975

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause a denial of service (DoS) conditions.

The vulnerability exists due to an error in FoFiType1C::convertToType0 function in FoFiType1C.cc when processing documents. A remote attacker can send a specially crafted document, trigger NULL pointer dereference and perform a denial of service attack.

Successful exploitation of the vulnerability may allow an attacker to cause application crash.

Mitigation

Update the affected packages.
app-text/poppler to version: 0.61.1
