Title: PCRE vulnerabilities
Summary: PCRE vulnerabilities
Tavis Ormandy and Will Drewry discovered multiple flaws in the regular
expression handling of PCRE. By tricking a user or service into running
specially crafted expressions via applications linked against libpcre3,
a remote attacker could crash the application, monopolize CPU resources,
or possibly execute arbitrary code with the application's privileges.
Instructions: After a standard system upgrade you need to reboot your computer to
effect the necessary changes.
Due to the large internal code changes needed to solve outstanding flaws,
it was not possible to backport all the upstream security fixes to the
earlier released versions. To address this, the pcre3 library has been
updated to the latest stable release (7.4), which in

Multiple PCRE flaws
Tavis Ormandy of the Google Security Team reported multiple pcre regular
expressions flaws. Here are the details pasted from Tavis' mail:
CVE-2007-1659:
unmatched \Q\E sequences with orphan \E codes can cause the compiled
regex to become desynchronized, resulting in corrupt bytecode that may
result in multiple exploitable conditions. This was inadvertently
fixed by the pcre maintainer in version 7.0, however another case of a
lone \E inside a character class remained, this has been fixed in 7.3
CVE-2007-1660:
multiple forms of character class had their sizes miscalculated on
initial passes, resulting in too little memory being allocated, this
was also inadvertently fixed in version 7.0, where the compile phase
was entirely re-engineered (and much improved, from a sec
