pcre regular expression flaws

Perl-Compatible Regular Expression PCRE library before 7.0 does not properly calculate sizes for unspecified "multiple forms of character class", which triggers a buffer overflow that allows context-dependent attackers to cause a denial of service crash and possibly execute arbitrary code...

pcre integer overflow

Integer overflow in Perl-Compatible Regular Expression PCRE library before 6.7 might allow context-dependent attackers to execute arbitrary code via a regular expression that involves large 1 min, 2 max, or 3 duplength values that cause an incorrect length calculation and trigger a buffer overflo...

This update has been rated as having important security impact by the Red Hat Security Response Team. PCRE is a Perl-compatible regular expression library. Flaws were discovered in the way...

pcre miscalculation of memory requirements if options are changed during pattern compilation

Perl-Compatible Regular Expression PCRE library before 7.0 does not properly calculate the amount of memory needed for a compiled regular expression pattern when the 1 -x or 2 -i UTF-8 options change within the pattern, which allows context-dependent attackers to cause a denial of service PCRE or...

pcre miscalculation of memory requirements for repeated subpattern containing a named recursion or subroutine reference

Perl-Compatible Regular Expression PCRE library before 6.7 does not properly calculate the compiled memory allocation for regular expressions that involve a quantified "subpattern containing a named recursion or subroutine reference," which allows context-dependent attackers to cause a denial of...

PCRE: Multiple vulnerabilities

Background PCRE is a library providing functions for Perl-compatible regular expressions. Description Tavis Ormandy Google Security discovered multiple vulnerabilities in PCRE. He reported an error when processing "\Q\E" sequences with unmatched "\E" codes that can lead to the compiled bytecode...

openSUSE 10 Security Update : pcre (pcre-4697)

Specially crafted regular expressions could lead to a buffer overflow in the pcre library. Applications using pcre to process regular expressions from untrusted sources could therefore potentially be exploited by attackers to execute arbitrary code CVE-2007-1659, CVE-2007-1660. %NASLMINLEVEL 7030...

CVE-2006-7227

Integer overflow in Perl-Compatible Regular Expression PCRE library before 6.7 allows context-dependent attackers to execute arbitrary code via a regular expression containing a large number of named subpatterns namecount or long subpattern names maxnamesize, which triggers a buffer overflow. NOT...

pcre incorrect memory requirement computation

Perl-Compatible Regular Expression PCRE library before 6.2 does not properly count the number of named capturing subpatterns, which allows context-dependent attackers to cause a denial of service crash via a regular expression with a large number of named subpatterns, which triggers a buffer...

Important: Red Hat Security Advisory: pcre security update

Updated pcre packages that correct security issues are now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having important security impact by the Red Hat Security Response Team. Updated 15 November 2007 Further analysis of these flaws in PCRE has led to the single C...

pcre security update

CentOS Errata and Security Advisory CESA-2007:0967 Updated pcre packages that correct two security flaws are now available for Red Hat Enterprise Linux 5. This update has been rated as having critical security impact by the Red Hat Security Response Team. PCRE is a Perl-compatible regular...

DEBIAN-CVE-2007-1659

Perl-Compatible Regular Expression PCRE library before 7.3 allows context-dependent attackers to cause a denial of service crash and possibly execute arbitrary code via regex patterns containing unmatched "\Q\E" sequences with orphan "\E" codes...

Debian DSA-1400-1 : perl - heap overflow

Will Drewry and Tavis Ormandy of the Google Security Team have discovered a UTF-8 related heap overflow in Perl's regular expression compiler, probably allowing attackers to execute arbitrary code by compiling specially crafted regular expressions. %NASLMINLEVEL 70300 C Tenable Network Security,...

FreeBSD : perl -- regular expressions unicode data buffer overflow (5b47c279-8cb5-11dc-8878-0016179b2dd5)

Red Hat reports : A flaw was found in Perl's regular expression engine. Specially crafted input to a regular expression can cause Perl to improperly allocate memory, possibly resulting in arbitrary code running with the permissions of the user running Perl. %NASLMINLEVEL 70300 C Tenable Network...

Debian DSA-1399-1 : pcre3 - several vulnerabilities

Tavis Ormandy of the Google Security Team has discovered several security issues in PCRE, the Perl-Compatible Regular Expression library, which potentially allow attackers to execute arbitrary code by compiling specially crafted regular expressions.
