ckolivas/lrzip

A security vulnerability has been detected in ckolivas lrzip up to 0.651. This vulnerability affects the function ucompthread of the file stream.c. Such manipulation leads to null pointer dereference. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.

A vulnerability was found in ckolivas lrzip up to 0.651. This impacts the function lzma_decompress_buf of the file stream.c. Performing a manipulation results in use after free. Attacking locally is a requirement. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.

A security flaw has been discovered in ckolivas lrzip up to 0.651. This impacts the function __GI_____strtol_l_internal of the file strtol_l.c.
