{"id":"CVE-2026-13705","summary":"Imager versions before 1.032 for Perl have a heap out-of-bounds read in the bundled Imager::File::SGI reader via a 16-bit RLE literal run in read_rgb_16_rle","details":"Imager versions before 1.032 for Perl have a heap out-of-bounds read in the bundled Imager::File::SGI reader via a 16-bit RLE literal run in read_rgb_16_rle.\n\nread_rgb_16_rle guards each literal run with if (count \u003e data_left), but count is a pixel count while every 16-bit sample consumes two bytes. The copy loop reads inp[0] * 256 + inp[1] and advances two bytes per pixel, so a run with data_left / 2 \u003c count \u003c= data_left passes the guard yet consumes 2 * count bytes and reads past the end of the buffer. The 8-bit path is unaffected because there one pixel is one byte.\n\nReading a crafted SGI image through Imager-\u003eread triggers the over-read before the parser rejects the malformed image, which can crash the process.","modified":"2026-07-08T08:12:22.449623497Z","published":"2026-07-06T12:03:38.513Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13705.json","cwe_ids":["CWE-125"],"cna_assigner":"CPANSec"},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/07/06/3"},{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/13xxx/CVE-2026-13705.json"},{"type":"ADVISORY","url":"https://metacpan.org/release/TONYC/Imager-1.032/source/Changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-13705"},{"type":"FIX","url":"https://github.com/tonycoz/imager/commit/f28de02770dfc26ffbdc32048970ed84babbf730.patch"},{"type":"PACKAGE","url":"https://github.com/tonycoz/imager"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tonycoz/imager","events":[{"introduced":"0"},{"fixed":"ce585a7bde35da11c9ad019b75996b39a4f882bd"},{"fixed":"f28de02770dfc26ffbdc32048970ed84babbf730"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.032"}]}}],"versions":["v1.031","v1.030","v1.029","v1.028","v1.027","v1.026","v1.025","v1.024","v1.023","v1.022","v1.021","v1.020","v1.019","v1.018","v1.017","v1.016","v1.015","v1.014","v1.013","v1.012","v1.011","v1.010","v1.009","v1.008","v1.007","v1.006","v1.005","v1.004_004","v1.004_003","v1.004_002","v1.004_001","v1.004","v1.003","v1.002","v1.001","v1.000","v0.99_02","v0.99_01","v0.99","v0.98","v0.97","v0.96_02","v0.96_01","v0.96","v0.95","v0.94_02","v0.94_01","v0.94","v0.93","v0.92","v0.91","v0.90","v0.89","v0.88","v0.87","v0.86","v0.85_02","v0.85_01","v0.85","v0.84_02","v0.84_01","v0.84","v0.83","v0.82_01","Imager-0.82","Imager-0.81","Imager-0.80","Imager-0.79","Imager-0.78","Imager-0.77","Imager-0.76","Imager-0.75","Imager-0.72","Imager-0.71","Imager-0.65","Imager-0.63","Imager-0.61","Imager-0.60","Imager-0.59","Imager-0.58","Imager-0.55","Imager-0.53","Imager-0.52","Imager-0.51_02","Imager-0.51_01","Imager-0.49","Imager-0_38pre9","Imager-0_38"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-13705.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"}]}
