Out-of-bounds read vulnerability in Apache Arrow Rust (`arrow` crate), from version 33.0.0 through to versions 57.3.1, 58.4.0, 59.3.1 and 60.0.0. Improper validation of RunEndEncoded arrays in the ArrayData interface can allow reading data beyond the bounds of the child values array. Users are recommended to upgrade to versions 60.1.0, 59.3.2, 58.4.1, 57.3.2 which fixes the issue.

———The Sleuth Kit through 4.15.0 contains a heap out-of-bounds read vulnerability in hfs_load_extended_attrs() in tsk/fs/hfs.c that reads the decmpfs header without checking attribute length. Attackers can supply a crafted HFS+ image with a com.apple.decmpfs attr_size of 1 to 15 to read past the allocation and crash analysis tools like istat or icat.4h

——0In ip_stack, there is a possible out of bounds read due to improper input validation. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01387180; Issue ID: MSV-5152.4h
