Affected: AlmaLinux:8: pam, AlmaLinux:8: pam-devel

Pluggable Authentication Modules (PAM) provide a system to set up authentication policies without the need to recompile programs to handle authentication.

Security Fix(es):

* linux-pam: Linux-pam directory Traversal (CVE-2025-6020)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions.

A crafted self-referential DOS partition table will cause all Das U-Boot versions through 2019.07-rc4 to infinitely recurse, causing the stack to grow infinitely and eventually either crash or overwrite other data. In Das U-Boot versions 2016.11-rc1 through 2019.07-rc4, an underflow can cause memcpy() to overwrite a very large amount of data (including the whole stack) while reading a crafted ext4 filesystem. Das U-Boot versions 2016.09 through 2019.07-rc4 can memset() too much data while reading a crafted ext4 filesystem, which results in a stack buffer overflow and likely code execution. An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy when parsing a UDP packet due to a net_process_received_packet integer underflow during an nc_input_packet call. An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with an unvalidated length at nfs_readlink_reply, in the "if" block after calculating the new path length. An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length check at nfs_read_reply when calling store_block in the NFSv2 case. An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with unvalidated length at nfs_readlink_reply in the "else" block after calculating the new path length. An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length check at nfs_lookup_reply. An issue was discove…

Affected: openEuler:22.03-LTS-SP3: pam

PAM (Pluggable Authentication Modules) is a system of libraries that handle the authentication tasks of applications (services) on the system. Security Fix(es):

Linux-pam is a plug-in and unplugged system authentication software for Linux teams. There is a security vulnerability in Linux-pam. This vulnerability originates from insufficient protection when using user control paths by the pam_namespace module, which may cause local users to be elevated to root permissions through symbolic link attacks and race conditions.(CVE-2025-6020)
