Fedora 23: Critical Flex Update for Buffer Overflow Issue

Change type for num_to_read from yy_size_t to int.. -------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2016-8d79ade826 2016-12-09 19:11:08.399542 -------------------------------------------------------------------------------- Name : flex Product : Fedora 23 Version : 2.6.0 Release : 2.fc23 URL : Summary : A tool for creating scanners (text pattern recognizers) Description : The flex program generates scanners. Scanners are programs which can recognize lexical patterns in text. Flex takes pairs of regular expressions and C code as input and generates a C source file as output. The output file is compiled and linked with a library to produce an executable. The executable searches through its input for occurrences of the regular expressions. When a match is found, it executes the corresponding C code. Flex was designed to work with both Yacc and Bison, and is used by many programs as part of their build process. You should install flex if you are going to use your system for application development. -------------------------------------------------------------------------------- Update Information: Change type for num_to_read from yy_size_t to int. -------------------------------------------------------------------------------- References: [ 1 ] Bug #1360743 - CVE-2016-6354 flex: buffer overflow in generated code (yy_get_next_buffer) https://bugzilla.redhat.com/show_bug.cgi?id=1360743 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program. Use su -c 'dnf upgrade flex' at the command line. For more information, refer to the dnf documentation available at https://dnf.readthedocs.io/en/latest/command_ref.html All packages are signed with the Fedora Project GPG key.

Debian Jessie DSA-3653-2 Critical: Flex Buffer Overflow Fix

It was reported that the update for flex as released in DSA-3653-1 did not completely address CVE-2016-6354 as intended due to problems in the patch handling and regenerated files during the build. Additionally a regression was introduced, causing new warnings when compiling flex . - ------------------------------------------------------------------------- Debian Security Advisory DSA-3653-2 This email address is being protected from spambots.

Additionally a regression was introduced, causing new warnings when compiling flex generated code. Updated packages are now available to address these problems. For reference, the relevant part of the original advisory text follows. Alexander Sulfrian discovered a buffer overflow in the yy_get_next_buffer() function generated by Flex, which may result in denial of service and potentially the execution of code if operating on data from untrusted sources. Affected applications need to be rebuild. For the stable distribution (jessie), this problem has been fixed in version 2.5.39-8+deb8u2. We recommend that you upgrade your flex packages.

Debian 3.1 DSA 1020-1 Critical: Flex Buffer Overflow Threat

Updated package.. - --------------------------------------------------------------------------Debian Security Advisory DSA 1020-1 This email address is being protected from spambots. You need JavaScript enabled to view it. http://www.debian.org/security/ Moritz Muehlenhoff March 28th, 2006 http://www.debian.org/security/faq - --------------------------------------------------------------------------Package : flex Vulnerability : buffer overflow Problem-Type : local Debian-specific: no CVE ID : CVE-2006-0459 Chris Moore discovered that flex, a scanner generator, generates code, which allocates insufficient memory, if the grammar contains REJECT statements or trailing context rules. This may lead to a buffer overflow and the execution of arbitrary code. If you use code, which is derived from a vulnerable lex grammar in an untrusted environment you need to regenerate your scanner with the fixed version of flex. The old stable distribution (woody) is not affected by this problem. For the stable distribution (sarge) this problem has been fixed in version 2.5.31-31sarge1. For the unstable distribution (sid) this problem has been fixed in version 2.5.33-1. We recommend that you upgrade your flex package.
