CVE-2008-1367

UnknownEPSS 2.79%

Last modified

CVE-2008-1367 is a vulnerability of currently unknown severity. gcc 4.3.x does not generate a cld instruction while compiling functions used for string manipulation such as memcpy and memmove on x86 and i386, which can prevent the direction flag (DF) from being reset in violation of ABI conventions and cause data to be copied in the wrong direction during signal handling in the Linux kernel, which might allow context-dependent attackers to trigger memory corruption. NOTE: this issue was originally reported for CPU consumption in SBCL.. EPSS estimates a 2.79% chance of exploitation in the next 30 days.
