However, upstream advisory and joernchen advisory seems not the same. The first says: adding -D_FORTIFY_SOURCE=2 to the OSDEFS line in src/Makfile and rebuilding sudo will prevent the bug from being exploited. The second says: he above example shows the result of FORTIFY_SOURCE which makes explotitation painful but not impossible (see [0]). Without FORTIFY_SOURCE the exploit is straight forward. something should be corrected? -- Agostino Sarubbo ago -at- gentoo.org Gentoo/AMD64 Arch Security Liaison GPG: 0x7CD2DC5D
