Noroxi assessment
Priority: Monitor (action score 36/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 18.6% (FIRST EPSS); higher than 97.3% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: t1lib (Debian:3.1) 5.0.2-3sarge1; t1lib (Debian:4.0) 5.1.0-2etch1; xpdf (Red Hat:enterprise_linux:2.1::as) 1:0.92-19.el2.
Low priority for now. Upgrade to t1lib (Debian:3.1) 5.0.2-3sarge1; t1lib (Debian:4.0) 5.1.0-2etch1; xpdf (Red Hat:enterprise_linux:2.1::as) 1:0.92-19.el2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
Buffer overflow in the intT1_EnvGetCompletePath function in lib/t1lib/t1env.c in t1lib 5.1.1 allows context-dependent attackers to execute arbitrary code via a long FileName parameter. NOTE: this issue was originally reported to be in the imagepsloadfont function in php_gd2.dll in the gd (PHP_GD2) extension in PHP 5.2.3.
