The MakeEdge function creates an edge between one output tensor of the src node (given by output_index) and the input slot of the dst node (given by input_index). This is only possible if the types of the tensors on both sides coincide, so the function begins by obtaining the corresponding DataType values and comparing these for equality. However, there is no check that the indices point to inside of the arrays they index into. Thus, this can result in accessing data out of bounds of the corresponding heap allocated arrays. In most scenarios, this can manifest as unitialized data access, but if the index points far away from the boundaries of the arrays this can be used to leak addresses from the library. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0. Affects Leap 15.2 and Factory in both packages. Also tensorflow2 is in a lower version in Factory than in Leap, that shouldn't be the case References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2020-26271 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-q263-fvxm-... http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26271 https://github.com/tensorflow/tensorflow/commit/0cc38aaa4064fd9e79101994ce98... -- You are receiving this mail because: You are on the CC list for the bug.
