Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU31853
Risk: Low
CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2012-2812
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library. A remote attacker can create a specially crafted image, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected packages.

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: #VU1477
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2012-2814
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing images in the exif_entry_format_value function in exif-entry.c in the EXIF Tag Parsing Library. A remote attacker can create crafted EXIF tags in an image, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.

3) Out-of-bounds read
EUVDB-ID: #VU31851
Risk: Low
CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2012-2836
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the exif_data_load_data function in exif-data.c in the EXIF Tag Parsing Library. A remote attacker can create specially crafted EXIF tags in an image, trigger out-of-bounds read error and read contents of memory on the system.
MitigationUpdate the affected packages.

Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
4) Division by zero
EUVDB-ID: #VU31850
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2012-2837
CWE-ID:
CWE-369 - Divide By Zero
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to divide-by-zero error within the mnote_olympus_entry_get_value function in olympus/mnote-olympus-entry.c in the EXIF Tag Parsing Library. A remote attacker can perform a denial of service (divide-by-zero error) via an image with crafted EXIF tags that are not properly handled during the formatting of EXIF maker note tags.
MitigationUpdate the affected packages.

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.
5) Integer underflow
EUVDB-ID: #VU31848
Risk: High
CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID: CVE-2012-2841
CWE-ID:
CWE-191 - Integer underflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow in the exif_entry_get_value function in exif-entry.c in the EXIF Tag Parsing Library. A remote attacker can create a specially crafted file and execute arbitrary code via vectors involving a crafted buffer-size parameter during the formatting of an EXIF tag, leading to a heap-based buffer overflow.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
MitigationUpdate the affected packages.
