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: https://security.gentoo.org/glsa/200505-08 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.
