Slackware Security[slackware-security] stunnel (SSA:2026-216-01)
New stunnel 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/stunnel-5.80-i586-1_slack15.0.txz: Upgraded.
This update fixes security issues:
Fixed an out-of-bounds memory access triggered by logging attacker-
controlled protocol messages longer than 1,024 bytes.
Fixed a SOCKS server mode bypass of the localhost destination filter
using alternate local-address encodings and interface-scoped IPv6
destinations.
