CVE-2020-7064: Use-of-uninitialized-value in exif
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 4.2% (FIRST EPSS); higher than 91% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: apcu-panel (AlmaLinux:8) 5.1.17-1.module_el8.3.0+2009+b272fdef; libzip (AlmaLinux:8) 1.5.2-1.module_el8.4.0+2229+b272fdef, 1.5.2-1.module_el8.3.0+2009+b272fdef, 1.5.2-1.module_el8.5.0+152+112d3b8c; libzip-devel (AlmaLinux:8) 1.5.2-1.module_el8.4.0+2229+b272fdef, 1.5.2-1.module_el8.5.0+152+112d3b8c, 1.5.2-1.module_el8.3.0+2009+b272fdef.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to apcu-panel (AlmaLinux:8) 5.1.17-1.module_el8.3.0+2009+b272fdef; libzip (AlmaLinux:8) 1.5.2-1.module_el8.4.0+2229+b272fdef, 1.5.2-1.module_el8.3.0+2009+b272fdef, 1.5.2-1.module_el8.5.0+152+112d3b8c; libzip-devel (AlmaLinux:8) 1.5.2-1.module_el8.4.0+2229+b272fdef, 1.5.2-1.module_el8.5.0+152+112d3b8c, 1.5.2-1.module_el8.3.0+2009+b272fdef or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In PHP versions 7.2.x below 7.2.9, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while parsing EXIF data with exif_read_data() function, it is possible for malicious data to cause PHP to read one byte of uninitialized memory. This could potentially lead to information disclosure or crash.

No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
