Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU32602

Risk: Medium

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

CVE-ID: CVE-2013-4473

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the extractPages function in utils/pdfseparate.cc when processing a source filename. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
app-text/poppler to version: 0.24.5

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) Input validation error

EUVDB-ID: #VU32603

Risk: Medium

CVSSv4.0: 5.5 [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:P/U:Green]

CVE-ID: CVE-2013-4474

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

Format string vulnerability in the extractPages function in utils/pdfseparate.cc in poppler before 0.24.3 allows remote attackers to cause a denial of service (crash) via format string specifiers in a destination filename.

Mitigation

Update the affected packages.
app-text/poppler to version: 0.24.5

3) Buffer overflow

EUVDB-ID: #VU42107

Risk: Medium

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:Green]

CVE-ID: CVE-2013-7296

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The JBIG2Stream::readSegments method in JBIG2Stream.cc in Poppler before 0.24.5 does not use the correct specifier within a format string, which allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted PDF file.

Mitigation

Update the affected packages.
app-text/poppler to version: 0.24.5
