Severity: Normal Title: HT Editor: Multiple buffer overflows Date: May 10, 2005 Bugs: #91569 ID: 200505-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Two vulnerabilities have been discovered in HT Editor, potentially leading to the execution of arbitrary code. Background ========== HT is a hex editor, designed to help analyse and modify executable files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-editors/hteditor < 0.8.0-r2 >= 0.8.0-r2 Description =========== Tavis Ormandy of the Gentoo Linux Security Team discovered an integer overflow in the ELF parser, leading to a heap-based buffer overflow. The vendor has reported that an unrelated buffer overflow has been discovered in the PE parser. Impact ====== Successful exploitation would require the victim to open a specially crafted file using HT, potentially permitting an attacker to execute arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All hteditor users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-editors/hteditor-0.8.0-r2" Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-08.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
