CVE-2026-88053
Description détaillée
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadIntTemplates in src/classify/intproto.cpp reads NumClassPruners, NumClasses, and NumProtoSets from the TESSDATA_INTTEMP component of a crafted .traineddata file and uses those values as loop bounds without validating them against MAX_NUM_CLASS_PRUNERS, MAX_NUM_CLASSES, and MAX_NUM_PROTO_SETS. The loops store heap pointers into fixed-capacity ClassPruners and ProtoSets arrays in INT_TEMPLATES_STRUCT and INT_CLASS_STRUCT, so an oversized count causes heap out-of-bounds pointer writes during legacy-classifier initialization before OCR begins, resulting in heap corruption, a crash, or potentially controlled corruption. No fixed release is available as of this review.

CVE-2026-88765
GitLab has remediated an issue in GitLab EE affecting all versions from 12.3 to 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 under certain conditions could allow an authenticated user to achieve remote code execution by importing a specially crafted Git project export to overflow the Unicode conversion buffer used in Advanced Search indexing.
CVE-2026-85234
A flaw was found in tftp-hpa. When the `in.tftpd` remap engine processes an inverse remap rule that also aborts with a non-empty custom error message, it can pass invalid match offsets to the `genmatchstring()` function. This leads to out-of-bounds read/write operations. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted request, causing the daemon to crash and resulting in a denial of service.
CVE-2026-82837
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 10.1.0 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 that certain conditions could have allowed an authenticated user to access sensitive credentials and tokens without transiting the expected proxy due to improper authorization checks on internal data emission endpoints.
