Return early if the Y position is off-screen and clip image height to screen boundary. Break from the rendering loop if the X position is off-screen. When clipping image width to fit the screen, update the character count to match the clipped width to prevent buffer size mismatches.  Without the character count update, bit_putcs_aligned and bit_putcs_unaligned receive mismatched parameters where the buffer is allocated for the clipped width but cnt reflects the original larger count, causing out-of-bounds writes.",null,[],[],[],[14],{"_key":15},"CVE-2025-40304",[],[],[],"2025-12-08T01:16:02.567Z","2026-04-28T20:30:29.871550Z",{"cisa_kev":22,"cisa_ransomware":22,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[24],{"url":25,"sources":26,"tags":28},"https://security-tracker.debian.org/tracker/CVE-2025-40304",[27],"osv_debian",[29],"Advisory",[],[],[],[34,55],{"ecosystem":35,"name":36,"vendor":37,"product":36,"cpe_part":9,"purl_type":38,"purl_namespace":37,"purl_name":36,"source":9,"versions":39},"Debian","linux","debian","deb",[40,46,49,52],{"version":41,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":44,"version_end_type":45,"fixed_in":9},"lt5_10_247_1",true,"ecosystem","5.10.247-1","excluding",{"version":47,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":48,"version_end_type":45,"fixed_in":9},"lt6_1_159_1","6.1.159-1",{"version":50,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":51,"version_end_type":45,"fixed_in":9},"lt6_12_63_1","6.12.63-1",{"version":53,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":54,"version_end_type":45,"fixed_in":9},"lt6_17_8_1","6.17.8-1",{"ecosystem":35,"name":56,"vendor":37,"product":56,"cpe_part":9,"purl_type":38,"purl_namespace":37,"purl_name":56,"source":9,"versions":57},"linux-6.1",[58],{"version":59,"is_range":42,"range_type":43,"version_start":9,"version_start_type":9,"version_end":60,"version_end_type":45,"fixed_in":9},"lt6_1_159_1~deb11u1","6.1.159-1~deb11u1"]
