Subject: libext2fs: fix potential memory leak in ext2fs_initialize()
X-Git-Tag: v1.41.1~142
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=adc4e77d89d9a423c3fbe6457676b020c9ad3a64;p=thirdparty%2Fe2fsprogs.git

libext2fs: fix potential memory leak in ext2fs_initialize()

If we fail doing ext2fs_allocate_block_bitmap() or
ext2fs_allocate_inode_bitmap() we directly goto cleanup and don't free
the memory allocated to buf.
