Noroxi assessment
Priority: Monitor (action score 27/100)
- 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: 6.5% (FIRST EPSS); higher than 93.9% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: php5 (Debian:5.0) 5.2.6.dfsg.1-1+lenny14; php5 (Debian:6.0) 5.3.3-7+squeeze5; php5 (openSUSE:Tumbleweed) 5.6.28-1.1.
Low priority for now. Upgrade to php5 (Debian:5.0) 5.2.6.dfsg.1-1+lenny14; php5 (Debian:6.0) 5.3.3-7+squeeze5; php5 (openSUSE:Tumbleweed) 5.6.28-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Integer overflow in the exif_process_IFD_TAG function in exif.c in the exif extension in PHP 5.4.0beta2 on 32-bit platforms allows remote attackers to read the contents of arbitrary memory locations or cause a denial of service via a crafted offset_val value in an EXIF header in a JPEG file, a different vulnerability than CVE-2011-0708.
