Tss2_RC_SetHandler and Tss2_RC_Decode both index into layer_handler with an 8 bit layer number, but the array only has TPM2_ERROR_TSS2_RC_LAYER_COUNT entries, so trying to add a handler for higher-numbered layers or decode a response code with such a layer number reads/writes past the end of the buffer. (CVE-2023-22745)

Mageia 2023-0048: editorconfig-core-c security update

data:image/svg+xml,%3Csvg%20xmlns=%22http://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

Mark Esler and David Fernandez Gonzalez discovered that EditorConfig Core C incorrectly handled memory when handling certain inputs. An attacker could possibly use this issue to cause applications using EditorConfig Core C to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-0341)

Mageia 2023-0046: libzen security update

A vulnerability classified as problematic has been found in MediaArea ZenLib up to 0.4.38. This affects the function Ztring::Date_From_Seconds_1970_Local of the file Source/ZenLib/Ztring.cpp. The manipulation of the argument Value leads to unchecked return value to null pointer dereference.

A null pointer dereference issue was discovered in 'FFmpeg' in decode_main_header() function of libavformat/nutdec.c file. The flaw occurs because the function lacks check of the return value of avformat_new_stream() and triggers the null pointer dereference error, causing an application to crash. (CVE-2022-3341)

gitattributes are a mechanism to allow defining attributes for paths. These attributes can be defined by adding a '.gitattributes' file to the repository, which contains a set of file patterns and the attributes that should be set for paths matching this pattern. When parsing gitattributes, multiple integer overflows can occur when there is a huge number of path
