CVE-2008-1367

Publication date 17 March 2008

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.

Notes

jdstrand

glibc part should be glibc 2.7-7 only use a low priority, since gcc-4.3 seems to be what is triggering it
