Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU32696

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-2012-5668

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via vectors related to BDF fonts and the improper handling of an "allocation error" in the bdf_free_font function.

Mitigation

Update the affected package freetype.

Vulnerable software versions

Slackware Linux: 13.0 - 14.0

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) Buffer overflow

EUVDB-ID: #VU32698

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-2012-5669

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The _bdf_parse_glyphs function in FreeType before 2.4.11 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to BDF fonts and an incorrect calculation that triggers an out-of-bounds read.

Mitigation

Update the affected package freetype.

3) Buffer overflow

EUVDB-ID: #VU43155

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-2012-5670

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The _bdf_parse_glyphs function in FreeType before 2.4.11 allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) via vectors related to BDF fonts and an ENCODING field with a negative value.

Mitigation

Update the affected package freetype.
