CVE-2020-14410: SDL (Simple DirectMedia Layer) through 2.0.12 has a heap-based buffer over-read in Blit_3or4_to_3or4__inversed_rgb in video/SDL_blit_N.c via…
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: 1.6% (FIRST EPSS); higher than 77.2% 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: libsdl2 (Debian:10) 2.0.9+dfsg1-1+deb10u1; libsdl2 (Debian:12) 2.0.14+dfsg2-2; libsdl2 (Debian:9) 2.0.5+dfsg1-2+deb9u1.
Low priority for now. Upgrade to libsdl2 (Debian:10) 2.0.9+dfsg1-1+deb10u1; libsdl2 (Debian:12) 2.0.14+dfsg2-2; libsdl2 (Debian:9) 2.0.5+dfsg1-2+deb9u1 or later.
