Descriptions

Integer overflow in the index.c:read_entry() function while decompressing a compressed prefix length in libgit2 before v0.26.2 allows an attacker to cause a denial of service (out-of-bounds read) via a crafted repository index file.

Desbordamiento de enteros en la función index.c:read_entry() mientras se descomprime una longitud de prefijo comprimida en libgit2, en versiones anteriores a la v0.26.2, permite que un atacante provoque una denegación de servicio (lectura fuera de límites) mediante un archivo de índice de repositorios manipulado.
