pcre2: Out-of-bounds read in compile_xclass_matchingpath in pcre2_jit_compile.c

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compilexclassmatchingpath function of the pcre2jitcompile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in...

OESA-2022-1686 pcre2 security update

PCRE2 is a re-working of the original PCRE1 library to provide an entirely new API. Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of...

An out-of-bounds read vulnerability was discovered in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. This involves a unicode property matching issue in JIT-compiled regular expressions. The issue occurs because the character was not fully read in case-less matching within JIT.

PCRE 缓冲区错误漏洞

PCRE is an open source regular expression library written in C by the individual developer Philip Hazel. A security vulnerability exists in PCRE. An attacker can exploit this vulnerability to trigger a denial of service or obtain sensitive information by forcing a read of an invalid memory addres...

kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation

A flaw was found in the Linux kernels eBPF implementation. By default, accessing the eBPF verifier is only accessible to privileged users with CAPSYSADMIN. A local user with the ability to insert eBPF instructions can abuse a flaw in eBPF to corrupt memory. The highest threat from this...

Detection evasion in CLR and tips on how to detect such attacks

In terms of costs, the age-old battle that pits attacker versus defender has become very one sided in recent years. Almost all modern attacks and ethical offensive exercises use Mimikatz, SharpHound, SeatBelt, Rubeus, GhostPack and other toolsets available to the community. This so-called...

Edge’s Super Duper Secure Mode benchmarked: How much speed would you trade for security?

In an attempt to make Edge more secure, the Microsoft Vulnerability Research team has started to experiment with disabling Just-In-Time JIT compilation in the browsers V8 JavaScript engine, to create what its calling Super Duper Secure Mode. The reasoning behind this experiment sounds valid. A...
