OESA-2021-1327 — leptonica security update

Affected: openEuler:20.03-LTS-SP2: leptonica

The library supports many operations that are useful on * Document images * Natural images Fundamental image processing and image analysis operations * Rasterop (aka bitblt) * Affine transforms (scaling, translation, rotation, shear) on images of arbitrary pixel depth * Projective and bi-linear transforms * Binary and gray scale morphology, rank order filters, and convolution * Seed-fill and connected components * Image transformations with changes in pixel depth, both at the same scale and with scale change * Pixelwise masking, blending, enhancement, arithmetic ops, etc. Security Fix(es): Leptonica before 1.80.0 allows a denial of service (application crash) via an incorrect left shift in pixConvert2To8 in pixconv.c.(CVE-2020-36277) Leptonica before 1.80.0 allows a heap-based buffer over-read in findNextBorderPixel in ccbord.c.(CVE-2020-36278) Leptonica before 1.80.0 allows a heap-based buffer over-read in pixFewColorsOctcubeQuantMixed in colorquant1.c.(CVE-2020-36281) Leptonica before 1.80.0 allows a heap-based buffer over-read in rasteropGeneralLow, related to adaptmap_reg.c and adaptmap.c.(CVE-2020-36279) Leptonica before 1.80.0 allows a heap-based buffer over-read in pixReadFromTiffStream, related to tiffio.c.(CVE-2020-36280)
