The Slackware Linux Security Team released SSA:2026-188-01 to address multiple vulnerabilities in the tftp-hpa package. Version 5.4 resolves uninitialized buffer reads, broken path tokenizers, and several buffer overflow flaws that allowed crafted requests to bypass directory restrictions or crash the daemon.

New tftp-hpa packages are available for Slackware 15.0 and -current to
fix security issues.

Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/tftp-hpa-5.4-i586-1_slack15.0.txz: Upgraded.
This update fixes bugs and security issues:
Fix several security-relevant bugs in path validation
(tftpd/path.c): an uninitialized buffer read and a broken
path tokenizer could let a crafted or unlucky request bypass
path restrictions or crash the daemon.
Fix buffer overflows in the tftp client: an unbounded strcpy()
when building requests, an out-of-bounds write when putting
multiple files to a remote directory, and an unbounded write
into the interactive command-line argument array.
Fix an out-of-bounds read while scanning request fields in
tftpd, and an incorrect address family used when creating the
per-transfer socket on platforms without recvmsg().
(* Security fix *)
