RHSA-2004:634 - Security Advisory

Synopsis

zip security update

Type/Severity

Security Advisory: Low

Topic

An updated zip package that fixes a buffer overflow vulnerability is now
available.

Description

The zip program is an archiving utility which can create ZIP-compatible
archives.

A buffer overflow bug has been discovered in zip when handling long file
names. An attacker could create a specially crafted path which could
cause zip to crash or execute arbitrary instructions. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-1010 to this issue.

Users of zip should upgrade to this updated package, which contains
backported patches and is not vulnerable to this issue.
